Rock and roll has always thrived on rebellion, energy, and heart. But every once in a while, a band comes along that shakes the entire scene not just with their music, but with their story. Enter The Warning, three sisters from Monterrey, Mexico, who are rewriting the rules of modern rock and proving that family chemistry and raw talent can ignite a global movement.
From Monterrey To The World
Daniela (vocals, guitar), Paulina (drums, vocals), and Alejandra Villarreal (bass) grew up surrounded by music. Raised in a household where classical training was encouraged, they mastered piano at an early age before falling under the spell of rock. The sisters bonded over their shared love of Metallica, Muse, and Foo Fighters, trading scales for power chords and drum fills.
Their big break came in 2014, when their cover of Metallica’s Enter Sandman went viral on YouTube. At just 9, 12, and 14 years old, the Villarreal sisters suddenly had the attention of millions, including Metallica themselves. But instead of becoming just another viral sensation, The Warning used the moment as a springboard to craft their own sound.
Carving Out Their Identity
Unlike many young acts who stick to covers, The Warning quickly proved they were songwriters at heart. Their debut album, XXI Century Blood (2017), tackled themes of technology and identity in a chaotic world, while its follow-up, Queen of the Murder Scene (2018), showed stunning maturity with its dark concept and cinematic storytelling.
By 2020, they signed with Lava/Republic Records, home to bands like Greta Van Fleet. The move gave them global exposure, but they never lost the grit that made them stand out in the first place. Their latest work, Keep Me Fed (2024), strikes a perfect balance between thunderous riffs and vulnerable lyrics, a statement that The Warning are more than just prodigies. They’re leaders of rock’s next generation.
A Live Force Of Nature
What truly sets The Warning apart is their live show. The sisters command the stage with an intensity that belies their youth, blending technical precision with pure emotion. Fans have witnessed their rise firsthand as they’ve opened for giants like Muse, Guns N’ Roses, and Foo Fighters, while also selling out their own headline tours.
Their three-night run at Mexico City’s Auditorio Nacional, immortalized in their concert film Live from Auditorio Nacional CDMX, proved they could stand shoulder-to-shoulder with the legends.
“Playing those shows in our home country was a dream come true,” Paulina told People. “It wasn’t just about us — it was about proving that Mexican rock can shine on the world stage.”
Breaking Barriers
As young women in rock, The Warning know they are defying expectations. They’ve spoken openly about the challenges of carving out space in a male-dominated industry, but their philosophy remains rooted in resilience and kindness.
“We always remind ourselves, stay humble, work hard, and never forget why we started,” Alejandra shared in a recent interview.
Their dual identity as Mexican artists who primarily write in English has also become part of their appeal. They embrace both cultures, proudly representing Monterrey while pushing into the global rock arena.
The Road Ahead
The Warning’s ambitions are as bold as their riffs. Stadium tours, bilingual projects, and bigger productions are all on the horizon. With each release, they’re not just keeping rock alive, they’re reshaping it for a new era.
And fans aren’t just listening; they’re connecting. Their music speaks to a generation grappling with anxiety, self-discovery, and resilience. In many ways, The Warning aren’t just a band, they’re a movement.
Why They Matter
- Sibling synergy: Their bond fuels a chemistry most bands can only dream of.
- Authenticity: They’ve grown publicly, from teenagers on YouTube to international stars, without losing their core identity.
- Representation: They’re proudly Mexican, proudly women, and proudly rock — expanding what the genre looks and sounds like.
- Final Word
The Warning are no longer “the sisters who covered Metallica.” They are global contenders, carrying the spirit of rock into the future with fire in their guitars and conviction in their voices. Monterrey gave them roots, but the world is their stage now.
If you haven’t yet, dive into Keep Me Fed or catch them live, because The Warning aren’t just making noise. They’re making history.
