I've checked far and wide and couldn't find any mention of this recording existing or being officially released. It's definitely not the same as the 1972 set. This was found in a stack of free reels at a record fair in San Francisco this past weekend along with one other seemingly uncirculated Art Blakey tape. Seems to be an FM recording, not sure if master or 1st gen. Not really familiar with the tunes, so I was only able to identify the ones announced.
