Query: A rare gem!

This 2-disc set from Blue Note showcases an very underated artist. Recorded over six days in 1956 these sessions sound fresh and showcase Criss's big alto sound on every cut. You can hear touches of bird and other big horn players in his bluesy style, but his rich voice seems to come from his great command (smooth, fleet & big tone) he has. Supporting players Kenny Drew, Sonny Clack, Larry Bunker, Barney Kessel never turn a wrong step. It's a shame Sonny Criss is not more widely known.These recordings have wonderful full (mono) sound throughout.
