Norbert Möslang had been playing in Voice Crack duo with Andy Guhl in 1972-2002, they’ve been working with “cracked everyday-electronics”, modifying and recontextualising the use of home electronics. After the split he continued working solo and in different musical combinations using “cracked everyday-electronics”, among them a duo with eRikm with whom he played in duo from time to time since 2002. He released numerous solo albums as well as collaborations with Günter Müller, Jason Kahn, Ralf Wehowsky, Tomas Korber, Aube, Christian Weber, Katsura Yamauchi. He is part of Signal Quintet and mkm. "sale_interiora" is his third album on Mikroton after "Stodgy" with eRikm and "Five Lines" with Casey Anderson, Jason Kahn, Günter Müller and Mark Trayle.

Ilia Belorukov hails from St. Petersburg and works mainly with prepared saxophone in the field of improvised, noise and electroacoustic music. He’s a member of different projects like Wozzeck, Mars-96 and others. He practices an experimental approach of sound extraction on alto saxophone and uses laptop, electric guitar, drums and other instruments. He also runs our partner Intonema label and organizes with us Teni Zvuka festival in St. Petersburg and Moscow.

In 2009 he joined his forces with Kurt Liedwart, a Moscow-based musician and curator of Mikroton Recordings and organizer of Teni Zvuka festival. When the duo started Liedwart was using only sinewaves and field recordings adding more sounds and noises with time. Liedwart works mainly with computer, electronics, synthesizer and objects, sometimes deleting the line separating concerts from performances or installations, at the same time he’s active in the fields of electroacoustic improvisation and sound art.

In 2014 they invited Norbert Möslang to take part at Teni Zvuka Festival, played two concerts in trio and made 4 hours of recording overall which formed thirty four minutes of "sale_interiora". The three musicians generate pulsing waves of rushing sound, piercing whisltes, bombastic microsound glossolalia, conjuring wide panoramas of sound colours and light streams.
