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.

"I have an old instument in my hand, a stone or a piece of wood. The different parts of the instrument have different sounds that can be played. The different sounds form for me a musical mode that I want to hear from all angles, just as I look at the stone to see properly what it looks like. Sounds like.
