I guess I should add that it looks like a prime set. I have almost all of the material already, scattered over various Bird and other CDs, but the sound is supposedly great, and it looks like a great way to experience Bird's Verve years in a continuous manner (the complete set always put me off with the massive amount of alternate takes). At least one reviewer on Amazon expressed the caveat that the Master Takes set is not truly complete--evidently Verve defined the parameters as dates led solely by Bird--hence some of the Afro-Cuban dates, "Repetition" (kind of odd, since it does show up on the "Master Takes With Strings" set), and the sides with Coleman Hawkins aren't here. In any case, if you can pick it up for free with your vouchers or at a greatly reduced price, yes, I think it would be well worth it. Lon, I believe, already has it and might be able to weigh in more effectively for or against than I.
