c‐base cosmic open stage
This has been a weekly event which I started in 2003 and continued until 2007 at the c‐base e.V. in Berlin. Others kept it going until 2010. The difference to other jam sessions and open stages was that the music played had to be royalty‐free and no‐one would get chased off stage for bad performance. Lots of nights have been recorded and remastered. Some of them survived.
