From Discogs.com : "H.N.A.S. (Hirsche Nicht Aufs Sofa) was founded by Achim P. Li Khan and Christoph Heemann in 1983. H.N.A.S.'s sound experimentation started in 1984 with a series of limited cassettes made for demonstration purpose or personal use. Their first LP release was "Abwassermusik" in 1985 (together with german experimental band Mieses Gegonge).
The group then recorded "Melchior" with Steven Stapleton, released on the United Dairies label the following year. Subsequent H.N.A.S. releases were mainly on their own Dom label."
"Gegenstände Fallen Zu Boden" was released by Dom Elchklang in 1994.
