Now that I take a closer look at the track listing, the Birdland set looks like a bit of a botch job...
So, this set includes (yet again) the February 9 session which has already turned up on countless other boots and was officially issued by Pablo on their European Tours box, where it's mistakenly attributed to Hamburg, November 25, 1962.
However, it doesn't include the Birdland session of June 2, 1962, so not the 'Complete' 1962 Birdland stuff at all... unless they mean the complete 'with Dolphy' as Eric isn't on the June session. These Andorrans get cunning with their descriptions of things.
I suspect there are more 'Unreleased recordings' in the pipeline (the 1963 Birdland sessions will surely follow).
