I saw Coleman live a few years ago an Enjoy Jazz in Mannheim and I was impressed of the force he still had on stage at his advanced age. It really felt like this was the please he belonged to.
Indeed. At that age, it's expected that it will happen sometime. Since I was born far after the sixties, but love that period in jazz, I try to see as many musicians of that period/generation as possible.
I am very happy/fortunate to have seen him at North Sea Jazz 2010. It was great and powerful. He was also scheduled for Jazz Middelheim 2012, but unfortunately had to cancel at the last moment. One of my other favorites, John Zorn, aptly filled the spot (since there definitely is a Coleman heritage in Spy vs. Spy, Naked City, Masada, etc.).
