Grönan Live 2026
The Warning
The Warning are a rock band from Monterrey, Mexico, made up of sisters Dany, Pau, and Ale Villarreal. They first gained international attention in 2014 when their cover of Metallica’s “Enter Sandman” went viral on YouTube. Since then, the band has forged their own powerful sound, blending hard rock, alternative, and progressive influences.
With four studio albums released, including their latest Keep Me Fed, The Warning have built a strong global following. Renowned for their electrifying live performances, emotional lyrics, and remarkable musicianship, they have toured extensively and shared stages with major acts such as Muse, Guns N’ Roses, Foo Fighters, and The Killers.
Don’t miss an intense summer night of rock when The Warning take over Gröna Lund’s Main Stage on Friday, June 26.
