The Warning in Barcelona

The Warning are a Mexican hard-rock trio formed in Monterrey in 2013 by sisters Daniela, Paulina and Alejandra Villarreal. They first drew wide attention through their cover of Metallica’s “Enter Sandman” and later established their own catalogue through albums including Queen of the Murder Scene, Error and Keep Me Fed, as well as songs such as “Choke,” “Evolve” and “More.” In 2022, The Warning opened for Foo Fighters at Foro Sol in Mexico City. The Error World Tour brought them headline dates across North America and Europe, while selected 2023 shows placed them in support of Muse on the Will of the People World Tour. The 2024 Keep Me Fed Tour also included performances at Download Festival and Wacken Open Air. The trio performs as a full rock band: Daniela handles guitar and lead vocals, Paulina plays drums and sings, and Alejandra plays bass and contributes backing vocals. The Warning play frequently in Mexico, the United States and Britain. They have headlined concerts in Los Angeles and London and returned to their home city for shows at Arena Monterrey.
