ARRM is an instrumental band from Sosnowiec whose music develops beyond the conventional form of a rock song. Their long, gradually unfolding compositions emerge from improvised sessions and are later transformed into multilayered structures built from guitar, synthesisers, piano, bass, double bass and drums.

The group’s sound brings together psychedelia, ambient, drone, krautrock and post-rock, as well as influences from spiritual jazz, folk, afrobeat, dub and contemporary electronic music. Following their self-titled debut album from 2016, ARRM released II, further developing their music towards more open, spacious and improvised forms.
