One of Nat Adderley's finest albums. Sometimes the inclusion of tuba in a small-group modern jazz setting can produce whale-like results among a school of dolphin, but that's not the case here. Tuba man Laymon Jackson doesn't dominate or weigh down the proceedings, but merely gives them another texture. Nat is in fine form; I like his Miles mode on BLUE CONCEPT a lot. Tune selection for the date is also top rate: the two compositions by Duke Pearson (WHAT NEXT? and LITTLE MISS) are especially good. Nat Adderley fans and modern jazz lovers in general should like this ambitious CD very much.
