Philo,
I saw the Ginger Baker documentary, too, and it's clear that there's just something wrong with the guy. I'm embarrassed to admit it, but I actually laughed when Ginger hit the interviewer with his cane at the end. They'd just spent several months together and seemed to have bonded (a bit), when Baker hauls off and whacks him. The poor guy just stands there bleeding and staring. It was awful and really not funny, but it was also just too bizarre for words.
OTOH, while Ginger Baker may be a pretty ugly human being, he can sure play the drums.
BTW, another name for this thread is Anton Fier of The Feelies and, later, The Golden Palominos. He was always providing interest and unexpected rhythmic flourishes for both of those bands.
