Thorns Ltd. is a Norwegian experimental/drone/art-circuit offshoot of the black metal band Thorns. The project was started in 2003 by Finn Olav Holthe (of The 3rd and the Mortal), Jon Wesseltoft and Snorre Ruch to explore the aesthetics of sound and its influence on the listener, using multichannel playback systems and various audio preparations.
The band first produced sound for Norwegian visual artist Bjarne Melgaard's works displayed at the Playlist exhibition at the Palais de Tokyo in Paris in 2004. Ruch and Holthe had previously contributed sound to Melgaard's Interface to God exhibition at Kunsthalle zu Kiel in 2002. Thorns Ltd. has later contributed sound to works by New York artist Banks Violette and others.
Holthe left the band in 2006. Ruch and Wesseltoft have continued as Thorns Ltd. in addition to their work in Thorns. Wesseltoft also performs and records solo and with other bands such as Maranata and Cock of Corpse.
