Deathprod is a musical pseudonym used sometimes by Helge Sten from Røros, Norway for his ambient-influenced music. On recordings, he 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 began creating music under this name starting in 1991, culminating with a box set of most of his recorded work being released in 2004.
