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 the compositional process, Bishop employed both hardware equipment and software including retro tape recorders, modular synthesizers, samplers and a diverse array of other tools. Bishop´s alias when making ambient experimental music is Tortusa, and Betula in club music contexts. He is part of the groups Beatpop, Skolekorps and The Afeeliated.
For several years, Bishop has been composing and performing for modern dance and performance art shows in Norway, England and France. He has made music for short films «Limerence», «Hyperspace» and «Across the dreams». Aside from making music Bishop works with photography.
