ARRM
An instrumental band from Sosnowiec. Their music goes beyond the confines of the classic rock song structure. Long, gradually building up compositions originate from improvised sessions before transforming into multi-layered structures built upon guitar, synthesizers, piano, bass, double bass, and drums. The group’s sound blends psychedelia, ambient, drone, krautrock, and post-rock, while drawing inspiration from spiritual jazz, folk, Afrobeat, dub, and contemporary electronica. Following their 2016 self-titled debut, ARRM released the album “II”, further developing their music toward even more open, spacious, and improvised forms.

Simon Grab
A Swiss sound artist, musician, composer, and sound designer. He creates music for film, theatre, dance, and radio; in his concerts and installations, he treats the existing space as an acoustic playground. His sonic language is rooted in noise, sonic detritus, feedback, and deep, pulsating bass frequencies.
Grab engages in transdisciplinary projects, combining improvisation with other art forms and musical contexts. He is interested in sound systems that operate on the boundary between control and autonomous behavior, as well as in transcending established divisions between noise, dub, performance art, and sound art. His recordings have been released by labels such as -OUS Records, LavaLava Records, and Sound-Space.

Piotr Kaliński – Hatti Vatti
A Gdańsk-based electronic music producer, guitarist, and DJ. His work spans dub, ambient, IDM, UK bass music, and improvisation, blending electronic production with acoustic instrumentation. Kaliński is also involved in projects such as Hinode Tapes, Nanook of the North, and JANKA, and runs the experimental label Kanu Kanu Recordings.
In 2024, the Belgian label R&S Records released the album “Zeit”, recorded in collaboration with saxophonist Piotr Chęcki, bassist Paweł Stachowiak, and drummer Rafał Dutkiewicz. The material fuses dub, synth-based ambient, “kosmische Musik”, psychedelia, and contemporary jazz with echoes of Japanese electronic music. With this release, Hatti Vatti became the first Polish project to appear in the R&S Records catalogue.
