Saturday I was babbling excitedly to jazzfriends Nathalie and Ben about seeing Ornette Coleman's quartet at the last day of the Jazz Middelheim festival, in August. Today I learn that he collapsed on stage from a heat stroke. I hope he'll still be able to make it over here. Last year, Andrew Hill had to cancel his Blue Note Records Festival engagement and didn't get a second chance. Darcy links to Jon Pareles's eyewitness account.
