"Breakthrough" and "Song Everlasting" are the 2 Don Pullen/George Adams Quartet BN dates. There are a number of "solo" Adams and Pullen albums on BN, but I would suspect that the Select box would only be the Quartet. This group seemed to go under the name George Adams/Don Pullen Quartet on the other labels. Same combo no matter what - Cameron Brown and Dannie Richmond round it out.
Which reminds me, I have an album on HORO under Richmond's name with Pullen, Adams, Jack Walrath, David Friesen, Irio de Paula and Afonso Vieira. Could they ben including that, too?
Should be interesting.
