Bjørn Hatleskog is a London based artist making sound sculptures and releasing music under the moniker Romvelope. His work is located somewhere between electro acoustic music and sound sculptural bricolage. It explores the nature of feedback loops, noise and interference and their relationship with music. These ideas are examined through the construction of modular devices which are combined to form semi-autonomous musical instrument cum sound installations, which function like machines or very primitive computers. They have a programs in the form of a binary code represented visually by the wooden pegs on the discs. But instead of doing something useful like adding numbers or making calculations they generate strange sounds. These installations are in turn used as the basis for musical compositions.
