Masterpiece? Really? I've had that one for about 40 years now, and it's pretty much the same handful of somewhat slight ideas over and over. He makes it all "sound good", but there's a not a whole helluva lot of filling in that pie.
Backing off on this some for the record. Been revisiting it fairly heavily the last few days, and although I still think "masterpiece" is too much (needs stronger soloists and more "stable" time to qualify in my book), it is a distinctive work of integrity...and more or less totally un-Kentonish in its vibe. Some of the tunes would not be out of place on, say, Sonny's Dream. Barton's writing showed this inclination back in 1962 on his "Turtle Talk", and if many of the charts have a general overall "sameness" (not so much literally, but attitudinally), so be it. This guy, Barton, was writing charts that reconciled many of the conceptual ideas of "new jazz" with the Kenton instrumentation. More importantly, somehow, some way, the whole thing about Kenton getting nervous about shit swinging too much (true!) got left aside here - the band swings hard, and Barton is driving the bus.
Soloists are definitely playing "catch up" to the last 5 or 6 years from 1967, but...they're cool. At least they recognized what was going on and that it mattered. So many others in this world didn't.
Truth be told, in a perfect world, Dee Barton & Charles Tolliver could have collaborated and the Music Inc. Big Band repertoire could have expanded significantly. For all kinds of reasons, that type of perfect world didn't exist then, doesn't exist now, and may never exist. But there's a lot of stuff on here that suggests that at heart Barton was leaning more towards Impact! than New Concepts Of Artistry In Rhythm, more Gerald Wilson than Bills Russo & Holman, and that the worlds of that (and this) time does not encourage such things is...too bad.
Masterpiece? Almost, not quite.
A worthy record? Most definitely.
Some of the very best jazz ever made under the name "Stan Kenton" ? Without question, and more truly "progressive" and "innovative" than most things bearing that name, because it's tied into the jazzworld of its time instead of trying to tie a rope around it.
Highly recommended? Oh hell yeah!
Never let it be said that I'm a man who does not reconsider when given good cause.
