Pretty good doc on John Coltrane.
Although some of the talking heads like former President Clinton and Carlos Santana are not useful and only distract from the subject. Clinton's only there cause he thinks he knows how to play the sax.
My biggest beef is with the section on 1965. Coltrane did not just up and invent a new avant-garde style. That came from contemporaries like Ornette Coleman (who is not even mentioned, and created what was known as "Free Jazz.") and some of the wild cats like Sun Ra and Rahsaan Roland Kirk (again none of them mentioned).
Coltrane surely heard those cats and was influenced by them. But the film fails to deliver that critical content.
