First of all, I prefer the MJQ with Connie Kay. This is really ancient MJQ, Chamber Jazz at the beginning. Not only very innovative for the time, but innovative for any time. There is still no group around today that plays like these guys. The arrangements are very tight, the playing is tight. When I used to go to see the MJQ play in the 60's, they looked tight. Very reserved, very focused, they took their music very seriously. And with the utmost of taste, including the tuxedos. This album is the utmost of taste. Django is very deliberate and stiff as compared to others recordings by them, but this is the first one, so I've got to have it. One Bass Hit, Delaunay's Dilemma, Autumn in New York, all MJQ staples, debut here. Great work by Percy Heath throughout. If you are into the history of jazz, and you want a complete collection, you have to have this work.
