Ku! aptly define themselves as "something akin to the sensation of eating a caffeine-laced, potent mint gum", a flash of luminous rock with hints of lo-fi punk that defies any label. Formed over a slow fire since 2021 by members of key bands like Yo Diablo and Los Premios, their sound is an exciting, risky and original chop. After previews like Seis semanas and Calor, the band presents their long-awaited debut full-length, Ku! (2025), an album with all their winning cards on the table and a forceful live performance that fuses the nerve of Thee Oh Sees or Parquet Courts with reminiscences of early lo-fi pop.
