"Lonely Woman" is my jam. I can sort of get into some of the Cecil Taylor stuff, but I admit that a lot of it is waaaay out there for me. I don't know if Sun Ra counts as free jazz or not, but he's got a lot of great albums. Not a huge fan of Coltrane's avant garde jazz period. Him and Pharaoh Sanders screaming "Aaaaaaaaaa!" on tracks doesn't do it for me.
