Anatole Muster is a Swiss-born, London-based producer and accordionist whose inventive sound bridges jazz, nu-jazz, and jazztronica. Following a BBC2 feature in 2021, he quickly gained international recognition through collaborations with artists such as Louis Cole and Tennyson. Since then, Muster has performed at major festivals across Europe and beyond, and in May 2025 he released his highly anticipated second album, hopecore.
