In 1999, together Steve Heather and Cor Fuhler , Anne La Berge founded Kraakgeluiden, a improvisation series based in Amsterdam, exploring combinations of acoustic instruments, electronic instruments and computers, and using real-time interactive performance systems. Marko Ciciliani was also involved in organization and production in the later years of the series.

Many of its musical collaborations that have resulted have taken on a life beyond the Kraakgeluiden series, which ceased in 2006.

A CD release by Unsounds was only one of the many recordings that were made. The seven years of photo and audio archives from this weekly concert series still need to be sorted and catalogued.
