Abstract free jazz that is more than just an expressionistic blowing session (that's the free jazz that I rarely have a taste for). Although, gotta say, I take issue with the liner notes saying, "this 1965 French LP coined the phrase 'free jazz' before the American genre of the same name had fully taken shape'... Uh, no. Read a book, kids. Also, maybe pick up some Ornette Coleman (maybe even the one titled Free Jazz), and that's just for starters.
