Behind the Riffs and Romance: Netflix’s Intimate Documentary on The Warning Sisters

Netflix has officially greenlit a feature‐length documentary that dives into both the soaring careers and the private love lives of The Warning, the hard‐rocking trio of sisters from Monterrey, México. Announced in February 2025 via a fan community post, the project promises a candid look at how Daniela, Paulina and Alejandra Villarreal balance life on the road with the relationships they’ve built offstage

In this in‐depth article, we explore why Netflix is spotlighting The Warning’s romances, unpack the sisters’ meteoric rise, and preview multiple examples of the personal stories viewers can expect—ranging from long‑distance love to behind‑the‑scenes heart‑to‑heart conversations.

A New Chapter: Netflix’s Documentary Announcement

Netflix’s decision to chronicle The Warning’s personal lives marks a departure from conventional music documentaries, which often focus exclusively on performance footage or career milestones. Instead, this upcoming film aims to humanize the trio by showcasing the bonds they maintain with their significant others amidst relentless touring

“We often hear about bands ‘on the road,’ but not about who’s waiting back home,” the announcement teases, promising never‐before‐seen interviews and private video diaries.

The Warning Phenomenon: From Viral Sensation to International Rockstars

Formed in 2013 by sisters Daniela (guitar, lead vocals), Paulina (drums, vocals) and Alejandra (bass, vocals), The Warning quickly distinguished themselves with a fierce, guitar‐driven brand of hard rock. Their breakthrough came in 2014 when a cover of Metallica’s “Enter Sandman” went viral—earning praise from the thrash metal legends themselves and launching the sisters onto The Ellen DeGeneres Show and major festival stages worldwide

By 2024, they had:

• Signed to Lava Records (a Universal Music Group affiliate) and released their critically acclaimed album ERROR
• Supported rock icons such as Aerosmith, The Killers and Foo Fighters on arena tours
• Headlined sold‐out shows across North America and Europe, including stadium‐sized dates in Mexico City and Madrid

This documentary arrives at a pivotal moment: the sisters, now in their early twenties, stand at the intersection of global superstardom and personal maturation.

Spotlight on Love: Why Netflix is Digging Deeper

1. Humanizing Superstars

Audiences crave authenticity, and Netflix’s “You Can’t Make This Up” podcast underscores the streamer’s commitment to personal storytelling—turning viewers into empathetic participants in real lives, not just spectators of spectacle

2. Broadening Appeal

By weaving in narratives of romance and family, the documentary will attract not only rock fans but also viewers drawn to human‐interest stories—expanding The Warning’s reach beyond music platforms and into mainstream pop‐culture conversations.

3. Empowering Young Women

Daniela, Paulina and Alejandra serve as role models for young women worldwide. Showcasing how they maintain healthy relationships while pursuing demanding careers offers inspiration and practical insight to viewers facing similar life‐balance challenges.

What to Expect: Previewing the Romance-Focused Segments

A. Daniela’s Cross‑Continental Connection

In previously unseen footage, Daniela opens up about missing her boyfriend while on a European tour. Candid moments capture video‐calls in her tour bus, revealing the emotional toll of distance—and the small rituals (late‐night playlists, handwritten postcards) that keep their bond strong

B. Paulina’s Partnership and Compromise

Drummer and co‐lead vocalist Paulina reflects on negotiating tour schedules with her partner’s work commitments. An intimate scene in her London hotel room shows her reading supportive messages from home, underscoring the behind‑the‑scenes compromises that sustain their relationship

C. Alejandra’s Circle of Support

Alejandra, the youngest sister, highlights how her boyfriend and family form a “support network” that grounds her after electrifying performances. Home‐video clips—including a surprise airport welcome in Monterrey—illustrate the steadfast encouragement fueling her confidence onstage

Contextual Examples: Why These Love Stories Matter

• Maintaining Identity: Despite the whirlwind of fame, each sister speaks to preserving their individual selves within relationships—a theme echoed in their Allison Hagendorf interview, where they confirmed having “people waiting back home”
• Work‑Life Balance: The documentary will explore practical strategies—time‑management routines, joint travel days, shared hobbies—that help the brothers and sisters of The Warning keep romance thriving alongside relentless tour dates.
• Emotional Resilience: By spotlighting moments of vulnerability (late‑night tears, missed milestones, reconciliations), Netflix aims to show not a perfect rockstar fantasy, but real emotional resilience

Reasons Behind Netflix’s Narrative Choice

1. Proven Engagement: Previous Netflix documentaries—from Dancing for the Devil to Trigger Warning—demonstrate that audiences engage deeply with personal narratives, particularly when they reveal new facets of well‑known figures
2. Social Media Amplification: Teaser clips highlighting romantic moments will be primed for viral sharing, boosting the series’ visibility across platforms like TikTok and Instagram.
3. Franchise Potential: Given The Warning’s already announced follow‑up album and world tour, Netflix may position the documentary as the first in a multi‐part series, tracking future relationship milestones alongside career achievements.

Anticipated Impact on Fans and the Band’s Image

By peeling back the curtain on their private lives, the documentary stands to:

• Deepen Fan Loyalty: Fans will feel a closer kinship, having witnessed the sisters’ authentic joys and struggles.
• Attract New Viewers: Viewers outside the hard‑rock sphere—drawn by human‑interest appeal—may discover The Warning’s music through Netflix’s platform.
• Shape the Band’s Legacy: Future retrospectives will reference this doc as the moment when the world saw The Warning not just as musicians, but as multidimensional individuals.

Conclusion

Netflix’s forthcoming deep‑dive into The Warning’s love lives represents a strategic convergence of music biopic and relationship documentary. By combining electrifying concert footage with tender, off‑stage moments, the film promises to deliver a 360° portrait of three sisters who rock the stage—and the hearts of those who love them. Whether you’re a diehard metalhead or a fan of intimate storytelling, this documentary is poised to resonate on every beat.

The Warning: “This is a testament to the influence of music and the connection it establishes with people, irrespective of their language”

The Warning’s fourth album, Keep Me Fed, was a huge success last year. Since then, they’ve been touring nonstop. The Villarreal Vélez sisters are poised for worldwide success as they prepare to compete in Latin America and Europe.

Following The Warning’s performance at the MTV Europe Music Awards in Manchester in November, the Villarreal Vélez sisters flew to Miami for the Latin GRAMMYs.

“That week, the way we lived it, it was just so crazy,” drummer Pau laughs now.

“Very chaotic,” explains bassist Ale.

“It was a lot,” says lead vocalist and guitarist Dany.

They were nominated for Best Push at the EMAs, which honours breakthrough acts. The band performed Automatic Sun, from their fourth album Keep Me Fed, drenched in crimson light and interrupted by bursts of fire.

Speaking to Kerrang! from their home base in Monterrey, Mexico, some months after the back-to-back concerts, the three sisters are animated, completing each other’s sentences or giving overlapping responses.

“It was just so hectic and full of adrenaline,” Pau exclaims. “I don’t think we’ll ever forget that whole week.”

At the Latin GRAMMYs, The Warning dressed in metallic clothes and played Qué Más Quieres, which was nominated for Best Rock Song, as strobe lights shone overhead. The band members are natural Spanish speakers who generally write and perform in English. They make it a point to include one Spanish tune on each album, which was nominated on Keep Me Fed.

“We toured a lot in North America, Europe, and even Asia,” Pau says of the previous year’s whirlwind. “But we hadn’t visited South America in a while, not even Mexico. So to be honoured in the Latin American society by our colleagues, particularly our rock’n’roll peers, and to be representing Mexican music, we feel really honoured.”

To call it a hectic period would be an understatement. After releasing Keep Me Fed last summer, The Warning’s popularity skyrocketed, putting them on worldwide platforms such as awards events, TV screens, and even New York’s famed Times Square. It’s especially amazing given that Dany, Pau, and Ale are only 25, 23, and 20 years old, respectively. And, as Pau explains, they’ve travelled so much that they’re familiar with some of their roadside stops.

“Touring North America, we know what it is, we’ve done it for a while,” Pau tells me. “We know our stops, Walmarts, and Targets. “We know where to go.”

“The only thing was the cold in Canada…” Ale adds.

The first phase of the tour included a journey across the United States, including festivals and headline gigs, followed by support positions in Canada with Halestorm and Evanescence, the former of which The Warning had previously played with. “It was just like reuniting with old friends,” Pau tells me.

By the time Kerrang! meets up with the three, they’re reaching the conclusion of a much-needed trip break before the entire machine goes back into gear.

“We’ve been here in Monterrey for a while, and again, we’re about to leave, but I feel that leaving and touring just makes me really appreciate my home, my city,” proclaims Pau.

At home, their celebrity is apparent and, simply, inevitable. It’s warning-mania.

“Every time we leave our house, we get asked for a picture or an autograph,” Pau tells me. “It doesn’t bother me since I’m aware of its presence. I am aware that this will happen when I go out, yet it still surprises me at times.”

One occasion, the drummer was approached by a fan at a restaurant when she was paying the bill.

“There’s the other part, where you assume people are coming to you because they recognise you and they want to tell you something,” Dany recounts.

“But then they ask, ‘Hey, is your car the grey one that’s parked behind?'” I’m like, “Oh!” “I got ahead of myself,” Pau says, laughing.

The band’s 2024 travels were only the beginning of the Keep Me Fed cycle; this year, they’ll continue to tour extensively across continents.

“We’re super-excited about getting this album to the places that haven’t heard it completely,” Dany tells me.

On the day we meet, they’re just a week away from some very massive home-country gigs, including three nights at Mexico City’s 10,000-person Auditorio Nacional. This tour, together with a special local event at the 8,000-seat Auditorio Citibanamex, has totally sold out. Not that it has sunk in yet.

“We’re going to be living these shows that we’ve been planning for a whole year,” Pau tells me. “It’s this weird anticipation and anxiety – we’ve been living with the concept for such a long time, rehearsing for them, planning them, working with so many people to make them happen, and now they’re going to happen!”

After Mexico, The Warning will tour South America in March before going to the UK and Europe in April, including a performance at London’s O2 Academy Brixton.

“We’re from the opposite side of the planet,” Pau continues, “so having more than a thousand people buy tickets to see us at each event in places we’ve only been once or twice is insane to us. It demonstrates the power of music and its ability to connect with people regardless of language or location.”

The Warning have extensive experience performing in both large and local venues. These days, they go between opening for the likes of Guns N’ Roses and Muse, to their own performances, changing as required, but always attempting to make it as memorable and enormous as possible.

“Production-wise, it’s like, ‘Will that fourth screen fit onstage? Probably not. “So you just remove that type of thing,” Pau says. “But we have the same setlist and intensity. It doesn’t matter whether we’re performing for 300 or 3,000 people; the principle is the same for us. “It is the same experience.”

There’s another aspect to playing away from home. They basically become ambassadors.

“When we have an appearance at a festival or someplace that rarely has Mexican guests, we do feel that we’re representing our country as a whole,” Pau tells me.

“Even though, of course, we have just a tiny little bit of what Mexican music has to offer,” Dany concurs.

Many of The Warning’s listeners may have encountered Mexican rock music for the first time.

“We strive to represent our nation in the finest light possible, because we come from such a lovely country with such beautiful culture and history and music,” Pau explains.” “Mexican rock is a really distinct music that I hope people from other parts of the globe start exploring since it’s such a rich genre with such a long history. It’s wonderful that we can be a part of it, even if only in small ways. Hopefully, we can open that door in people’s thoughts, making them intrigued about what more Latin America has to offer.

In between touring and releasing an album, The Warning has been playing with other bands. Pau collaborated with Dead Poet Society on the song HURT during the Aftershock Festival last year. When they arrived in Mexico City, she and Dany repeated the process.

Another Aftershock link, The Warning worked with Japanese band Band-Maid, whom they met at the event in 2022 and toured with last year. The two bands began working on a song together via Zoom in December 2023, with The Warning going to Japan to finish it in May (the single, SHOW THEM, was released in August).

In the accompanying song video, each member competes with their instrumental counterpart, while Dany and Band-Maid vocalist Saiki Atsumi exchange all-English vocals.

“It was very interesting to see how both of us were using a language that was not our native one,” Pau tells me. “They speak Japanese; we speak Spanish. So it was about finding a common ground in another language, making it work musically, and communicating musically.”

However, it made nailing the lines more difficult.

“We would select a word, and they would say, ‘That doesn’t mean the same thing in Japanese English.'” We’re like, “What?” What do you mean? It’s the kind of stuff that translates really differently in other people’s music.”

Show Them, a song about refusing to be little and striving to be as large as you can be, was an uplifting listen, supported by its explosive swagger. “Ultimately, music literally became the language,” according to Dany.

This partnership, as well as The Warning’s general popularity, demonstrate that fans’ tastes extend beyond their native nations and languages.

“I feel that now, because of social media and the way that things are connected, we stop looking at music as this foreign export or import,” says Pau. “It’s just this way to communicate, and music from different places in the world is just so different because the language is different, and the phonetics are different.”

This approach is especially vital in a multilingual band.

“We can make music in English and we also make it in Spanish,” according to Pau. “For people to look at those two sides that we have, and for them to consume it in the same way, it’s really cool for us.”

It’s a little early for The Warning to start planning their future album, but when questioned, they do have some ideas.

“I want to have more than one song in Spanish,” Pau tells us.

“Let’s do that!” Ale agrees.

After a year, the three sisters are still able to remain grounded. “We keep a very big balance of knowing where we are, knowing where we were, and…”

“Where we can be,” Dany adds to Pau’s notion.

Of course, having relatives nearby helps. Not only do the band members play important roles, but so do their parents, especially when touring. Pau describes their mother as “a professional mom,” and their father works as a stage manager and audio engineer. Of course, no one can keep your ego in check better than a sister.

“I feel that we keep each other humble,” Pau explains.

“We complement each other,” Dany explains.

“When we rehearse, we know how to call each other out while also recognising the steps that we’re taking,” Pau tells us. “We do that with everything in the band.” “I think we have a good balance.”

And it’s a balance that looks quite promising for the future.

“I think we’re going to be okay!”

The Warning perform at London’s O2 Academy Brixton on April 17. This interview first published in the spring 2025 edition of Kerrang!.
