This reminded me - I'm off to Jazz Summer School in less than 2 weeks now!!
So, last year I spent most of the time with Martin Speake (alto Sax) as tutor for our small group - he has worked with Paul Motian and he played us a few recordings and we did some Paul Motian tunes - I still have the charts - photocopies of the handwritten originals - some really nice stuff!!
For one of the tunes that we played in the evening Jazz Club, we were augmented by an electric viola player and it was a sort of open improvisation based on the tune, but with no chords...very interesting to play as bassist.
I think it was called "It should have happened a Long Time ago" ...?
