Sadly, that disc was not complete. Lots of alternates would make a decent cd. Maybe the Japanese have done it right. I think there are a total of 14 masters.
The lp version of Inner Space was a 2 disc set and the Collectables disc duplicates it as I remember it. The premise of Inner Space was to reissue Tones + 2 unissued titles + 2 tracks issued under Hubert Laws' name. If you really want to be complete, hunt down the 2 Laws Atlantics.
Pretty hard to beat the early Morton Victors with Mitchell, Dodds and Ory or the Wanderers/Bootblacks sessions with Mitchell, Ory, Dodds and Joe Clark. Morton should be credited for arranging his stuff and Lil Armstrong the the Wanderers/Bootblacks.
