Deathprod is a musical pseudonym used sometimes by Norwegian artist Helge Sten for his ambient-influenced music. Sten began creating music under this name starting in 1991, culminating with a box set of most of his recorded work being released in 2004. Simply titled Deathprod, the collection contains three albums along with a bonus disc of previously unreleased, rare, and deleted tracks. On recordings, Sten is usually credited with "Audio Virus", a catchall term for "homemade electronics, old tape echo machines, ring modulators, filters, theremins, samplers and lots of electronic stuff." Sten is a member of Supersilent and works as a producer on many releases on the Norwegian label Rune Grammofon. He has also produced Motorpsycho and has worked with Biosphere on an Arne Nordheim tribute album called Nordheim Transformed.
