Lichens (Robert Aiki Aubrey Lowe) couples analogue modular systems with voice, crafting improvised shows that create a trancelike state. Stian Westerhus has a reputation as one of Europe’s best abstract guitar stylists; his shows see him wield the guitar in unconventional ways, using noise, electronics and low-end throbs to create immersive pieces. Poland’s Alameda 4 is a psychedelic improvisational ensemble playing militant grooves contrasted with amorphous space sound experiments and jazz/rock structures.
