My new band is all about it. Its a 3 piece with a few set grooves, but the bandleader is about "improvisational audio soundscapes". We combine it with video and still image art, etc. He started as a soundtrack guy, but has expanded to playing live shows which are actually growing in popularity here. The first album I played on, I met the drummer and heard the music for the first time when I was ready to play in the studio. Just plug in, listen and play what you feel.
So far it works!
