OTOH, at the Berlin Jazz Fest last year, Anthony Braxton presented what I thought was a really good free jazz [Invalid or Expired Link Removed]. He had 60 musicians stroll through the [Invalid or Expired Link Removed] contemporary art and architecture gallery. In this case, there were some charts of a sort, sometimes, and a form, in the sense that the some or many or all of the groupings were pre-arranged, and where in the gallery they located was also, to some extent, planned, but after that, the music the listener experienced was very personalized, as the listeners and the performers wandered through the gallery. Many times I could hear a few different groups at the same time. At other times, if I got close enough to one of the larger ensembles, I could only hear one. What I found particularly interesting was how I would hear unanticipated climatic points, most of which were very brief, but happened fairly frequently. Kind of a free jazz performance art.
