The Warning: Rock’s Rising Sister Trio Redefining the Genre

In the heart of Monterrey, Mexico, three sisters—Daniela “Dany” (guitar, lead vocals), Paulina “Pau” (drums, vocals), and Alejandra “Ale” (bass, backing vocals) Villarreal—have taken the rock world by storm as The Warning. Formed in 2013, this sibling trio has evolved from young prodigies posting YouTube covers to global rock sensations, blending hard-hitting riffs, infectious melodies, and raw authenticity that captivates audiences worldwide.

The Warning’s journey began with their viral cover of Metallica’s “Enter Sandman,” which has amassed over 26 million views. At ages 14, 12, and 9, the sisters showcased a maturity and skill that caught the attention of music fans and industry insiders alike. Their appearance on The Ellen DeGeneres Show in 2015 earned them a grant to attend Berklee College of Music, solidifying their path as serious musicians. This early exposure laid the foundation for a career defined by relentless ambition and a refusal to be boxed in by stereotypes in the male-dominated rock genre.

Their discography reflects their growth. The 2022 album ERROR tackled themes of technology and societal pressures with tracks like “Choke” and “Animosity,” showcasing their signature thrash intensity and stadium-ready hooks. Their 2024 release, Keep Me Fed, pushed boundaries further, blending poppy, accessible tracks with some of their heaviest work yet, such as “Six Feet Deep” and “S!CK.” With over 175 million streams globally, Keep Me Fed marked the biggest album debut for an all-female rock group this decade, landing them at #1 on Billboard’s Emerging Artist chart.

The Warning’s live performances are where their magic truly shines. Their chemistry as sisters creates a telepathic connection on stage, delivering electrifying shows that have won over diverse audiences. From supporting icons like Muse, Guns N’ Roses, and Foo Fighters to headlining sold-out shows, including three nights at Mexico City’s Auditorio Nacional in 2024, they’ve proven their ability to command any stage. Their live album and concert film, Live from Auditorio Nacional, CDMX, released in August 2025, captures this energy with a 25-song setlist, earning praise for its raw power and production quality.

Beyond their music, The Warning’s story is one of resilience and sisterhood. They’ve navigated the pressures of fame while staying grounded, emphasizing kindness and connection in an industry often marked by competition. Their collaborative approach to songwriting, as seen in Keep Me Fed, reflects their openness to growth, working with producers like Dan Lancaster to refine their sound. Their Mexican roots subtly influence their music, with percussion elements adding a unique flair.

As they prepare for a 2026 world tour after rescheduling 2025 dates, The Warning continues to redefine what it means to be a modern rock band. Nominated for Latin GRAMMYs, MTV VMAs, and EMAs, they’re not just rising stars—they’re a force reshaping rock’s future, proving that passion, talent, and sisterly bonds can break any barrier.
