CD Rothenberg Hein Tammen – Bird Saw Buchla


SONIC FLOTSAM is taking off from Pauline Oliveros’ Apple Box approach, here the suitcase acts as the instrument. Together with its contact microphones it functions as a filter and amplifier for the sounds coaxed from its resonant body.


“Proprioception (Body Awareness 2017)” is an assemblage of historic imagery, 70’s experimental video practices, and modern-day chaotic audio procedures.

This the 18th iteration of the Irtijal International festival of Experimental Music in Beirut, Lebanon. It is determined to boost and support free improvisation, free jazz, contemporary classical music, post-rock, experimental electronic music, sound-art as well as many other attempts to explore new and uncharted territories in sound.

Membranes is an audiovisual installation and performance by Lukas Truninger + Nicola Hein. It consists of hybrid instruments – constructed from drum-skins and electronic components – as devices to turn written texts into pulses of light and percussive sound.

Michael Vorfeld’s sounds are generated by different light bulbs and actuating electric devices, and the rhythmic variety of the flickering and pulsing lights is directly transformed into a comprehensive and microcosmic electro-acoustic world of sound. Using Harvestworks’ new 8-channel sound cube (with 4 speakers each situated on floor and ceiling), Hans Tammen’s Prozesshansl software moves these sounds in three dimensions to create fragile and contrastive soundscapes surrounding the audience.
