Mattias Petersson is a composer and performer based in Stockholm. He is part of the vibrant computer music scene with a personal take on live coding and modular synthesis. His music has been performed worldwide and released on labels like Hallow Ground, Moving Furniture Records, CODEPENDENT, IDEAL Recordings and Fylkingen records. He works primarily with electronic music but has also written chamber music, a number of operas and music for dance performances. His music moves seamlessly between electroacoustic music, drone and noise with a rhythmically driven pulse. Mattias holds a diploma in electroacoustic composition from the Royal College of Music in Stockholm and since 2006 he works there as a senior lecturer in electroacoustic composition. Petersson has been working with various modular systems since 1999 and is particularly interested in how the instrument can manifest itself as a composition, and how digital and analog technology can aid in realtime explorations of such compositions.
