"The Berlin-based clarinetist and composer/performer focuses on a subtle musicality of sound and noise phenomena. As an autodidact he has developed dubious manners on his instrument. His music is rooted in abstractness, including increasingly an insidious expressivity and a pre-melodic quality. He works on the borderline of composition and improvisation, with a preference for long-term collaborations.

His projects are The International Nothing - clarinet duo with Michael Thieke (cd: Mainstream, ftarri 2006 / less action, less excitement, less everything, ftarri 2010 / the dark side of success, ftarri 2014), los glissandinos with klaus filip (cd: Stand clear, creative sources 2005), the magic i.D. - Song Project with margareth kammerer, christof kurzmann & michael thieke (cd/vinyl: Till my breath gives out, erstwhile 2008 / i'm so awake - sleepless i feel, staubgold 2011), duo with Burkhard Stangl (cd: Musik - ein portrait in sehnsucht, erstwhile 2009), the dogmatics with Chris Abrahams (lp: The sacrifice for the music became our lifestyle, monotype 2012), here comes the sun with gunter schneider & barbara romen (cd: Here comes the sun, mikroton 2012), Kommando Raumschiff Zitrone with Christof kurzmann (cd: First time ever i saw your face, quincunx 2006), duo with Bernhard Gal (cd: Going round in serpentines, charhizma 2005), rebecca with michael renkel (cd: Rebecca [two variations], charhizma 2003), No Furniture with Boris Baltschun and Axel Dörner (cd: No furniture, creative sources 2003), and (exceptionally) solo.

Kai has been the commander of Raumschiff Zitrone from 2000 to 2006, joined by christof kurzmann in 2002. Recently both commanders have been retired and closed the legendary raumschiff zitrone which has presented concerts of countless international artists. In 2001 he co-initiated together with gregor hotz and conrad noack berlin's experimental music platform www.Echtzeitmusik.De.

Kai was artist-in-residense at quartier21 (part of museumsquartierwien, vienna) in 2004. As a result of fruitful collaborations and good friendships vienna feels like a second home for him."

Boris Baltschun was born in 1974 in Hansestadt Bremen, Germany and is a improvisor, composer and sound artist. He is known for his work with Serge Baghdassarians in Splitter, and the trio Baghdassarians / Baltschun / Beins.
