I have to say that this is probably the finest thing I've got of Dizzy's on cd. Of all the Bebop, Cubop and big band recordings I own, this is the best example of what this man can do. Small group combos bring the best outta Diz, and he is in the greatist of company. He takes a standard like 'Russian Lullaby' and transports it into Bebop heaven! 'Frelimo' rides the latin/funk train, Bebop and Birks works never sounded better. Pass, Roker and Brown shine here, who needs anyone else when this quartet gets cookin?! September song melts my heart each time. The engineering on the recording is fantastic, you can hear a pin drop. Every nuance is captured. Pushing 60 when this was recorded, I dont think the timbre and excecution ever sounded better from Diz. One of my all time favourite Jazz discs.
