The title is pretty self explanatory, does anyone know of any free jazz with a good vocalist? I know vocals aren't at all common in free jazz, but I wanted to see what I could find.

Is that a thing? If it is, maybe it shouldn't be.

I'll give you something else here. Hart of Barf. Grindcore with Tenor Saxophone, drums, and vocals. It can come off like free jazz in a way, but it really is grindcore.

It's not all free jazz, but Mike Patton has done multiple titles with John Zorn.

I can't think of anything else.

in Don Cherry's albums there are vocals, but I don't think I'd call him a "good vocalist"
It's a sort of mantra/meditation chant
