Today would have been John Coltrane's 82nd birthday. Here he is playing Naima. And here is an interview from 1960. "The reason I play so many -- maybe it sounds angry, because I'm trying so many things at one time, you see -- I haven't sorted them out. I have a whole bag of things that I'm trying to work through and get the one essential, you know?" Here is a computer animation, to the tune of Giant Steps. And here is a robot playing the Giant Steps solo. Not as good as the original. Coltrane died in 1967, at the age of 40.
