"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.
