Convulsif is a Swiss experimental rock quartet that emerged in 2014 from Convulsif Bigband, a project initiated by bass player Loïc Grobéty. The band explores the tension between composition and improvisation, creating a powerful and constantly evolving sound world at the intersection of different musical languages.

With its distinctive instrumentation — a rhythm section formed by Loïc Grobéty on bass and Maxime Hänsenberger on drums, combined with heavily amplified and electronically treated violin and bass clarinet by Jamasp Jhabvala and Christian Müller — Convulsif develops a unique approach to contemporary rock. Doom, drone, black metal, noise and experimental music are transformed through composed structures, conceptual frameworks and improvisational processes.

Balancing density and openness, repetition and rupture, Convulsif creates a sound that is both physical and unpredictable, rooted in the energy of rock while continuously challenging its conventions.
