Heemann was a founding member of the anarchic noise-collage project H.N.A.S. (Hirsche Nicht Aufs Sofa), who released a string of bizarre, dada-inspired records during the mid 1980s. Heemann regards their 1987 release "Im Schatten Der Möhre" as the pinnacle of their recorded career.

The early 90s saw Heemann's first solo releases; within a decade he had built up a catalogue of records on labels such as Streamline label (see the label's own entry for more information) which has been busy releasing a diverse catalogue of records from artists such as Nurse With Wound, John Duncan, Ora and Andrew Chalk.
