Geneva, 2012. A riff explodes in the dim light of a basement. Bass and drums welded together like hot tarmac, a voice curling over it like acrid smoke: Cosmosonic is born from that collision, raw stoner streaked with flashes of metal and grunge.
2017: five tracks, one EP, zero compromise. Still burning, still streaming.
On stage, the band doesn't just show up: support slots for Monster Magnet, Monkey3, Mammoth Mammoth, My Sleeping Karma and Samavayo.
Cosmosonic shakes every stage it plays. Today, riffs sharpened and rage intact, Cosmosonic is back for good. Straight to the stage, straight into the fuzz.
Line-up: Arnaud (vocals), Bebert (guitar), Zuzu (guitar), Bourreau (bass), Moussu (drums).
Next show: Friday, November 13, 2026 — Good Rock Festival, Monthey.
