Af Ursin is the alter ego of Finnish autodidact composer/improviser Timo van Luijk. His work is rooted in the use of acoustic instruments (wind, percussion, strings), but his special sensitivity to the timbral qualities of each instrument, and his deft blurring of them, results in a sound-world that is mysterious, amorphous and hallucinatory, full of suggestive shadows, creaks and whispers.
