ZUZU, the founder
He’s been here since the first riff. In 2012, in Geneva, Zuzu laid down the foundations of a raw stoner, streaked with flashes of metal and grunge, with Cosmosonic. Fourteen years later, the frame still holds.
New line-up, same foundations.
MOUSSU, behind the drums
A founding member, Moussu has held the drum stool since 2012. He’s the one who gives the rhythm section that hot-tarmac density, welded to the bass.
ARNAUD, the new voice
Vocals that curl around the riff like acrid smoke: since spring 2026, they are his.
Arnaud Defigier takes the mic for Cosmosonic. You may already know him as the frontman of up-and-coming band Hashtag Bimbo; now he lends his voice to our songs.
See you on 13 November in Monthey to hear him live.

BEBERT, the new guitar
Albert Serrano, aka Bebert, joins Cosmosonic’s guitars alongside Zuzu. He earned his stripes with Colossus Fall and Code Of Conduct, two well-known names of the Swiss and Geneva metal scene.
A newcomer with the same appetite for heavy riffs: see you on 13 November in Monthey.
