KO KO MO

KO KO MO is a French power duo consisting of Warren Mutton (vocals, guitar) and Kevin 'K20' Grosmolard (drums). Formed in Nantes in 2012, they have carved out a niche as one of Europe's most electrifying live acts.

Their sound identity is built on a 'two-headed hydra' philosophy, where the lack of a bassist is compensated for by Mutton's thick, octave-divided guitar tones and Grosmolard's maximalist drumming style. Musically, they are rooted in the 1970s hard rock tradition, specifically drawing from Led Zeppelin and T. Rex, but they filter these influences through the lens of modern alternative and garage rock. Critical consensus highlights Mutton's extraordinary vocal range, particularly his comfort in a high-register falsetto that provides a melodic counterpoint to the aggressive instrumentation. They occupy a cultural space within the French 'Rock Hexagonal' scene alongside peers like Last Train and Skip The Use, representing a resurgence of guitar-driven music that prioritizes live energy over studio artifice. Their evolution from the raw 'Stole My Soul' EP to the more expansive 'STRIPED' shows a band refining their ability to blend vintage aesthetics with modern production clarity.
