Originally from Finland but now resident in Belgium, Timo van Luijk is an autodidact sound artist/composing improviser working with acoustic instruments (strings, wind, percussion) and various (sound) objects.

He started his musical excursions with some obscure local projects in the mid 80's and following sound studies/research he formed the experimental music/multimedia collective Noise-Maker's Fifes together with Geert Feytons in 1989. Simultaneously he slowly developed his personal musical activities as Af Ursin with regular releases since 1996.

Apart from his solo work he has done frequent collaborations with Christoph Heemann (In Camera) and Limpe Fuchs, Kris Vanderstraeten, Raymond Dijkstra (Asra), Andrew Chalk (Elodie), Frederik Croene and is member of the group Onde together with Greg Jacobs and Marc Wroblewski (both from Noise Maker's Fifes).
