I haven't heard it, or other Past Perfect boxes, but I've heard a few single discs. Sound quality was decent. This is likely a good, well priced intro to a lot of Bird sides, may do the ttick for you.
If you do wind up getting that box, Al, you might find this little story helpful.
B B King, in his autobiography, "Blues all around me", wrote that one evening, Dizzy Gillespie (who was a friend of B's), couldn't get Bird to the gig as usual, because Dizzy had something else to do. So he asked B B King to be Bird's chauffeur. King was reminiscing with Bird about when he'd seen him with the McShann band in Indianola. "I'm a blues player B," said Bird. "We're all blues players. It's just that we hear blues in different ways. The day we get away from blues is the day we'll stop making sense."
