He's talking about Ray Brown -
“After he moved to Los Angeles, we started working a lot together,” said Quincy Jones. “We got closer and closer. After a while, Ray started to take care of booking gigs and travel. He was an astute businessman. Old school played everything. We all played chitlin’ circuits. And you didn’t sit around whining about what you had to play, man. You played it, and tried to make it all sound good. That’s what I loved about Ray. That’s where I think our chord struck, in being very curious about what the business side of it was and not wanting to be a victim. We wanted to be more in charge of our own destinies.
“A man never plays more or less than they are as a human being, and Ray was a very confident, take-charge person. He played bass like that and lived like that. He ate 17 different dishes like that. Wherever we were, whatever was good, Ray knew what it was. He’d probably eat a 249-pound catfish if he tried! To me, he was the absolute symbol that if you empty your cup every time and learn to make it a habit, it always comes back twice as full. Give it up every time, man. Don’t save nothin’. I learned more and more about that from him all the time. In everything.”
