Mattias Petersson is based in Stockholm, where he studied electro-acoustic composition at the Royal College of Music. Besides this formal training, the more anti-academic Fylkingen community has had a big infuence on his works. In this context he has collaborated and played with a lot of other artists, as well as doing solo pieces in multi channel surround and other sound experiments.

His music has been described as a mix between ambient electronica, electro-acoustic, industrial and crackling noise. Since the critically acclaimed debut album "Mimer" (Fylkingen Records, 2003), which was based upon sounds from a defunct iron mine, Petersson's industrial soundscape has been mixed with piano and orchestra samples, treated through dirty filters, analog distortion and digital degradation. Mattias Petersson also released some CD-R:s on his own label "Wickerwork Recordings", and contributes with a track on the MP3 compilation "The Post_piano2 Open Remix Project" on the renowned label 12k.
