An audiovisual piece in which we look at the invisible and listen to the inaudible. With the help of an infra-red camera and coils that pick up electro-static fields, video and sound material is generated live. That material is then transposed into audible and visual range and further processed, manipulated and decorated. Premiered at Acker Stadt Palast, Berlin, May 2019.

web jamming🔗

Wanna form a virtual band?🔗

My idea has been to build a simple and easy to use framework for webjamming using the opensound control (OSC) protocol and SuperCollider by James McCartney. The framework now exists and it let members of our virtual band contribute with their favourite instruments, i.e. sounding patches written in SuperCollider, to be played by themself or by others live via the internet.

The number of people participating in this virtual band is varying from time to time and the overall structure is very loose. At its most, there have been seven players from both North America and Europe jamming together using this framework. And whenever there is a concert gig coming up, we just bring as many members as possible together over the net and makes sure there is one computer running the current set of instruments at the concert location. As no audio data is ever transferred, just control information, we have got no problems with latency or lousy audio quality due to compression.

The framework is currently based on a peer-to-peer network structure but that is subject to change in the near future. A client/server network has some significant advantages in this case mostly concerning the distribution of instruments within the network and dynamic connections. The new server application that I'm now working on will let people log in, share instruments with other connected players and jam using a simple SuperCollider client patch.

This piece is kind of ironic. Performed by KMH Jazz Orchestra in Feb. 1999, Conducted by Maria Schneider.


My very last 'jazz' composition became more of an acid jazz thing with heavy use of 'the amen breakbeat' drum loop. It was performed at the jazz festival in Sandviken 1999 and featured Lasse Lindgren on electrified trumpet.
