Ulrich Krieger (born 1962 in Freiburg) is a German contemporary composer, performer, improviser and experimental rock musician based in Los Angeles.
Krieger's artistic work spans a broad field from contemporary classical composition and free improvisation to experimental fusion with electronic music, rock, metal and noise. His special interest lies in the exploration of the physical fringes between acoustic and electronic produced sounds. In his music and with his instrument, the saxophone, he developed an original style of playing he calls "acoustic electronics". Acoustic electronics is about using sounds that appear to be electronic but are actually produced on acoustic instruments. His probably best known experimental project with acoustic electronics is the transcription of Lou Reed's guitar feedback opus Metal Machine Music, which he rearranged for chamber orchestra.
In his works for saxophone Krieger uses extended instrumental techniques, microsounds, electronic manipulation, and saxophone-controlled feedbacks. He defies stylistic boundaries, and the sonic result of this approach, as the Los Angeles Times critic Ann Powers describes it, "ranges wide as he seeks the spots where noise and beauty meet".
Krieger studied classical saxophone, composition, electronic music and musicology at the Manhattan School of Music (New York), the Universität der Künste (Berlin) and the Freie Universität (Berlin). He further pursued independent studies and research in the didjeridu and Australian Aboriginal music and culture. In his early years he studied in depth the contemporary music of the European post-war avant-garde and won related prices and residencies. Later he started to distinguish himself from the established New Music scene which in a 2007 interview he called "in a phase of mannerism and in a crisis".
