2016 two CD collection. Co-produced and with detailed liner notes by Phil Schaap, the world's pre-eminent Bird scholar, this collection features 58 previously unknown takes. These previously grounded performances provide unheard improvisations that, matched with their released editions, bring us into the working process of one of the greatest artists of our time. With 21 released masters providing context, this set dwarfs any previous Charlie Parker collection of rarities.
