Charles Mingus invited white Canadian folkie Joni Mitchell, of all people, to write lyrics for and record the last set of songs he composed before he died. If you need any more proof of the awesomeness of a man who wrote songs with names like “Pithecanthropus Erectus” or “The Shoes of the Fisherman’s Wife Are Some Jive Ass Slippers,” there you have it.
