" Carmell [Jones] was from L.A., and everybody’s nice in L.A., and friendly and sunny and everybody owns cars and has a parking space and all that stuff. He just wasn’t used to the East Coast. That week we’re at Pep’s. It was a Sunday afternoon, [and] we were going to do a matinee. Rudy Van Gelder was setting up, and Carmell was on the bandstand, which is in front of the bar. You know the way guys in Philly are. So these two guys . . . say “You’re the new guy, you’re the guy from sunny California. You better be able to play, man, after what Blue Mitchell played.” And they’re just ragging on him.
Any New Yorker, Philly or D.C. guy would just take that in stride and maybe come back at them. It crushed Carmell so badly that he just imploded for that whole day of recording. That’s what took the whole band down. He was just so sensitive and not used to the whole East Coast aggressive style . . . . It’s an aggressive style, but it’s mostly just people kidding each other. He crashed and burned and that took the whole thing down with him."
And further:
" Years later, Silver and Cuscuna spent an afternoon in a recording studio listening back to the recording. It was, in fact, so unissuable that Cuscuna relinquished the master tapes to Silver, who destroyed them."
