Just for quick review, the arrangers:
Gil Evans (Boplicity, Moon Dreams, Theme)
Gerry Mulligan (Jeru, Godchild, Deception, Venus De Milo, Rocker, Darn That Dream)
John Lewis (Budo, Move, Rouge, S'il Vous Plait, Why Do I Love You)
John Carisi (Israel)
I think it's interesting that people tend to think of this as mostly a Gil project (as far as the writing) when in fact he only arranged three of the tunes. I do think it was a Gil project inasmuch as these guys were constantly hanging out at Gil's place talking about the music, the instrumentation possibilities etc. with Gil assuming his svengali role (I would have loved to have been at some of those hangs!). IMHO the idea to use french horn and tuba very likely came at least in part from the time he spent in Thornhill's band and the sounds he was hearing there. I think anyone who enjoys BOTC should follow up by listening to Gil's Thornhill charts, especially Yardbird Suite, Anthropology and Donna Lee. It's amazing the degree to which he assimilated and personalized (Gil-ified) the bebop style when these tunes hadn't been around all that long. We've had decades to analyze these tunes and IMHO no one since has done any arrangements of those three Bird tunes that hold a candle to Gil's versions.
And Carisi's chart on Israel is a classic! I never tire of listening to it and use it as a model of contrapuntal writing for my arranging classes. Larry, you describe that piece perfectly!
Are there full scores available for all the BOTC charts?? I know there are transcriptions of the individual pieces available, but has anyone combined them into a book yet?
