The Warning is a Mexican rock band from Monterrey, formed in 2013 by the Villarreal Vélez sisters: Daniela (guitar, vocals, piano), Paulina (drums, vocals, piano), and Alejandra (bass guitar, backing vocals, piano). They have released four studio albums, two EPs.

They initially made waves with a string of independent releases, paving the way for their acclaimed 2022 full-length offering ERROR. Between performing alongside MUSE, Foo Fighters, Guns N´ Roses, Royal Blood, The Pretty Rockless, and Three Days Grace, the band ignited MTV’s Extended Play Stage at the 2023 MTV VMAs. Representative of their cultural impact, Pepsi even notably chose them as the face of Pepsi Black in Mexico. Moreover, they emerged as the rare force who could comfortably appear in features by Vanity Fair, People, Cosmopolitan, and Glamour as well as on Metallica’s star-studded Blacklist compilation—placing their cover of “Enter Sandman” [with Alessia Cara ] shoulder-to-shoulder with contributions from Ghost , St. Vincent, Chris Stapleton, IDLES, and Weezer .
