Christoph Heemann. Born in 1964 in Aachen, Germany, Heemann began his musical work in 1983 as a founding member of the group HIRSCHE NICHT AUFS SOFA (H.N.A.S.), who released several albums of their surreal collagemusic between 1985 and 1993, drawing inspiration from such diverse elements as musique concrete, avantgarde, krautrock and improvised music. After the group disbanded Heemann continued working solo and with the group MIMIR (with Edward Ka-spel and Jim O'Rourke), the drone projects MIRROR (with Andrew Chalk), and IN CAMERA (with Timo van Luyck).

Heemann's solo compositions have often been described as "ear-movies", in which he fuses field recordings, acoustic instruments, electronics, and electroacoustic sounds into audio narratives. Aside from this Heemann has done a series of musical collaborations (with Jim O'Rourke, Lee Ranaldo, Charlemagne Palestine, William Basinski) and works as a producer (Keiji Haino, Charlemagne Palestine, Limpe Fuchs, Current 93). He has run the Streamline label since 1994
