Last night I had the great pleasure of sitting in with Bik Bent Braam, a big band led by pianist Michiel Braam that focuses on free improvisation - making music up on the spot. This is a huge challenge with an ensemble of that size. We do that kind of thing with Kyteman's Hiphop Orchestra, but there we play mostly in one key, and Colin is in front of the band directing us.
With BBB everyone has the right to completely change the direction of the music at any time. Yesterday's concert was in the Bimhuis in Amsterdam, and for every set of 45 minutes, one BBB composition was played. The compositions were by Michiel, and were used as material or input during playing. The pieces were divided up into numbered sections so that anyone could signal a section to be played at some point during the improvisation. As such, we "played" the compositions, but never in the order they were written. It's a great way to break open the music and make it more free.
The difficult thing with free improvisation is to decide when to play, and what, and whether what you would like to play is valuable compared to whatever is already being played at that point. (Does that make sense?) Also, you want the music to go somewhere, which is hard enough when you play music that's not improvised.
Then again, I'm starting to think that judging your ideas while playing in this way may be the wrong approach entirely. Maybe you should just try to quit thinking and just play what you feel like playing.
Anyway, the band was great, and it was a really cool experience.
