My first introduction to Tony Williams was the Miles Davis album 'Miles in Europe.' Inconceivable to me that Tony was keeping time. He was playing his 'parts' (yes, plural) 'within' the time. (And killing it!) Elvin Jones with John Coltrane? More plural 'parts' within the time. (And more killing!) Max Roach played pstterns and melodies. Jimmy Cobb often played straight quarter notes on the cymbal. To me, that was his part in the music. And so on.....
