For you fans of Yellowjackets brand of jazz, this is a reference recording just like most of the other discs put out by Heads Up. The surrounds are used more for a wrap around type of effect instead of discretly. The music is great and as I said the sonics are just about as perfect as anything out there. I would give it a 98 out of 100 if I was measuring it on music and sonics combined. Hell, let's give it 100. I can't see how it would be improved.
