I think it came out and was a 2 disc set which included some broadcasts from Cafe Society as well. But the original Ember 4 disc set of the Birdland material is amongst Bird's best.
I'm curious: has anyone heard any Parker recordings they think are not worth having (for musical, not sound, reasons. ) Even the notorious Lover Man session on Dial has always seemed pretty interesting to me-- though maybe only for biographical reasons. If it were the only Bird available what would we think of him?
