Convulsif is a bass (sinister) and drums (diabolic) and a bass clarinet (vicious) and a violin (fierce). Yes, fierce, don’t let your little sister’s violin lessons trick you, classical instruments have an evil side, this band gives proof. Convulsif is dark and surprisingly addictive. A quartet of mad experimental extremists,Convulsif hunts down the perfect delirium made from doom, noise and drone, nightmarish, repetitive, ritualized. Relentlessly they take possession of your cortex and brand it with their monolithic sound. The band doesn’t fit in pre-established categories with their ultra complex, demanding and intense pieces. Why would you want to do something else if you can listen to Convulsif and go for a little walk in the cemetery with an axe ?
Line up :

In 2016, he released his K7  » Cri  » which included harshnoise and black metal works, on the labels Underground Pollution and Get a Life. Years of touring and intense collaborations followed, before moving back to introspection and composition in 2020. The pieces of « Sombre » offer his current sound vision. They are intended to be dark and cinematic to present epic, powerful, avant-garde drone, doom and noise soundscapes.
