One the whole, that band was mostly very square. Louder than shit and very aggressive, but take that away and it's usually very faux. Very.
But not always!
The really "bebop friendly" band was the so-called New Concepts band, which actually did swing. Konitz, Zoot, Kamuca, Rosolino, the Holman charts, a lot of non-stop heavy Russo, odds and ends from others. And other bands up until the end found their pockets, sometimes swinging traditionally, sometimes more uniquely. The later 60s into the early 70d bands were actually quite strong at this, imo.
The tell to it all, though, is something Al Porcino said about working the Kenton gig, that Stan would get a really good band and that they would get to swinging really good. And then, inevitably, Stan would look up and say, wait, this band is swinging, THIS IS NOT MY BAND!!!! And the he would get weird about it. But the cycle would always repeat.
It sounds funny, and it kinda is, but hey, this is the leader, the alleged visionary, and he doesn't have half an idea about how his band should be playing?
even at that, though, there were some good bands that made some really good records. But Stan Kenton himself was at best the enabler, not the creator. So... don't believe the hype, as they say. But do listen to the records, the good ones.
