I'll have to pick up the unedited Sound. I don't know why never knew that what is commercially available on CD differed significantly from the Delmark LP, which I picked up as I was just getting into jazz.
Thought that Graves was against having his music reissued while he was still alive, though with the NYAQ box that stance might have changed. The SRP records are cool, though I've long felt like they were "studies" for something we never got to hear. For example, their playing on More Giuseppi Logan is like the music from Yale, but fleshed out with reeds and bass.
