John Derek Bishop

John Derek Bishop (alias Tortusa) is a Norwegian-American electronic musician and producer from Stavanger, Norway. He has released seven albums on Jazzland Recordings and was nominated for the Spellemann Prize (Norwegian Grammy) for his solo album «I Know This Place». The albums har received good critics in the magazines Mojo, Prog Magazine, og Future Music. Bishop has collaborated with artist Arve Henriksen, Eivind Aarset, Jan Bang, Erland Dahlen, and more.

A cornerstone in Bishop´s production is the texture and timbre of sound. He searches for sounds that are out of the ordinary and places the listener in different emotional states. For compositional processes, he utilises both hardware and software equipment including retro tape recorders, modular synthesizers, samplers and a diverse array of other tools. His music is influenced by ambient, electronica and experimental jazz.
