Composer in acoustic and electroacoustic music. Musician in improvised music and Swedish folk music. Born 1968, Living and working in Uppsala. Educated at Gotlands tonsättarskola and The Royal College of music in Stockholm.

Wahlström has a background in a few types of improvised music in a few different collaborations. Meeting musicians and playing improvised music, Swedish folk music and folk music from other parts of the world has been a recurring and perspective-giving aspect of his compositional work and musicianship. In his compositions in contemporary art music and EAM, it may or may not be possible to hear connections between the different parts of his musical personality, but they are nevertheless operative.
