is an internationally recognized German composer and saxophonist living in Southern California. He is known for his originality and innovation in composed and free improvised contemporary music. As a celebrated composer of chamber and electronic music, Krieger’s compositions are widely performed by ensembles in Europe and the USA. He has been active in pushing the boundaries of saxophone playing in general and the function of the saxophone in rock and noise in particular, collaborating with Lou Reed (Metal Machine Trio, Lou Reed Band), Lee Ranaldo (Text of Light), Faust, and Merzbow, in addition to leading his own death-doom-noise-metal band Blood Oath. In his distinct style of amplified saxophone playing, Krieger processes refined acoustic and quasi-electronic sounds by amplifying his instrument in various ways. Krieger is professor for composition, Experimental Sound Practices, and rock music at CalArts, where his special field of interest is the cross-pollination of new art music and avant-garde rock.
