Another "revealing" anecdote - this once-young arranger I used to know told me that he was hanging with Basie after a gig and mentioned that he was an aspiring writer etc etc etc. Basie asks him who he likes as a writer, and the guy says Thad above anybody. Basie kind of winces and says, no no no...I don't like Thad's band, it sounds too much like Duke's.
So go figure. We got Liberace, shouting white guys, and Duke Ellington all as reason why people don't like it. I mean, c'mon, life is complicated, but it's not that complicated.
