What sad, sad news.
My first live encounter with Paul was in the late 70's. There was a club in midtown NY tham came and went quickly, called Storyville. They had a double bill of the Archie Shepp Quartet and Dewey Redman Quartet.
I was in town and went to find this club early, around 6 pm, and there was Motian alone unloading drums from a car. I offered to help, gave him a hand and then went on my way to have some food and came back later for the music.
At the end of the night when I asked for my bill ,I was told it was already paid. Paul had covered it.
I loved to play Paul's compositions and never tired of them.
Here's the last one I recorded, his ABACUS:
A simple, enigmatic theme, just the way his drumming could be.
