On Friday, 29 June, four Finnish experimental musicians invade Ptarmigan for an exploration of sound, space and improvisation.

Olli Aarni plays ambient music based on collage technique, samples and found sounds. His music under various monikers has been released by labels like Preservation, Under The Spire, Hooker Vision and Jozik.

Hur Hur is a solo music project by Timo Viialainen, featuring instruments such as hurdy gurdy, acoustic/electric guitar, trombone and different percussions & bells. The compositions combine looping and processing the sound of these instruments to form a backing material for improvised live performance. The result could be described as cinematic/cathartic ritual with the aim to create a powerful and psychedelic outcome. The influences of the project lie in the field of apocalyptic folk, primitive shamanistic music, electroacoustic experiments, drone & punk. http://soundcloud.com/hurhur
