Born in 1957 in Linz, Austria, he finished high school and piano studies at the Anton Bruckner Conservatoire in Linz and moved to Graz to study jazz piano, arranging and classical piano, as well as philosophy and German philology. Between 1977 and 1981 he worked with various jazzbands, including the Erich Zann Septet. After graduating from his piano studies, he began studying composition with Polish composer Andrzej Dobrowolski, who introduced him to the techniques of new music. He also studied counterpoint with Hermann Markus Pressl who introduced him to the work of Josef Matthias Hauer. In Graz, he met Gösta Neuwirth who was to become one of his main influences and who instructed him in composition for many years outside of the university setting. Georg Friedrich Haas introduced him to microtonal music and in 1988, commissioned a quartertone work for the Musikprotokoll festival.
Since 1988 he has been teaching music theory, harmony and counterpoint at the University of Music and Dramatic Arts in Graz, where he has been professor of composition since 2003. In 1998 he was a guest lecturer at the Peter Weibels Media Class at the University of Applied Arts in Vienna. In 2006 he was featured artist of the Wien Modern Festival in Vienna. At the Institute for Electronic Music in Graz, he developed the Loop Generator and the Visual Loop Generator with Winfried Ritsch and Thomas Musil. Since 2003 he has cooperated with various choreographers, including Xavier Le Roy, Christine Gaigg and Willi Dorner. He has also authored sound installations, including Schwarze Bänder at the 2005 Musica Viva.
His works have been performed at the Steirische Herbst Festival, Moscow Alternativa, Moscow Modern, Biennale Hannover, Tage Absoluter Musik Allentsteig I and II, Klangarten I and IV, Resistance Fluctuation Los Angeles, Summer Courses in Darmstadt, Salzburg Festival, Wien Modern, Donaueschingen, Witten and many others.
His main interest since 1999 is music theatre, derived from his interpretation of the ideas of difference/repetition: Theatre of Repetitions (2003), I Hate Mozart (2006), and The Old Man from the Mountain (2007). He also performs live as an improviser both solo and in duos. He currently lives in Vienna.
