Polish experimental musician Zbigniew Karkowski has died from cancer, after being diagnosed just a few months ago. He recently performed his final concert in London, a soundtrack to the 1950s BBC production of Nineteen Eighty Four at the Horse Hospital.

In the late 70s Karkowski became involved with a group of artists around the Radium label in Sweden, and studied in Gothenburg. He studied under Olivier Messiaen, Pierre Boulez and Iannis Xenakis, and worked at or was closely associated with both the EMS in Stockholm and STEIM (where he worked on gesture controlled instruments). In the 90s he moved to the Netherlands, and in 1995, to Tokyo, where he become heavily involved with the experimental noise scene.

Read two tributes to Karkowski by his friends, Atau Tanaka and Richard Whitelaw.
