I was trying to find a certain sound on the bottom end, going against the vogue at the time. It's very difficult to buck a vogue. Bass players were playing with dead strings; you couldn't get them to change to get a round, full-bodied tone. I liked that old analog, jukebox, Fifties sound-up-right bass, boomier. In the Sixties and early Seventies you had this dead, distant bass sound. I didn't care for it. And the other thing was, I had started to think, "Why couldn't the bass leave the bottom sometimes and go up and play in the midrange and then return?" Why did it have to always play the root? On "The Jungle Line" I had played some kind of keyboard bass line, and when it came around to Max Bennett having to play it, he just hated it. Because sometimes it didn't root the chord, it went up into the middle. To him that was flat-out wrong. To some people it was eccentric. So when Jaco came in, John Guerin said to me, "God, you must love this guy; he almost never plays the root!"
There was a time when Jaco and I first worked together when there was nobody I'd rather hang with than him. There was an appreciation, a joie de vivre, a spontaneity. A lot of people couldn't take him. Maybe that's my peculiarity, but then, I also have a fondness for derelicts.
He had this wide, fat swath of a sound. There weren't a lot of gizmos you could put your instrument through then, and the night I got my Roland Jazz Chorus amp, it was sort of a prototype. Jaco and Bobbye Hall and I were playing a benefit up in San Francisco. I tried playing through this thing and Jaco flipped for it. So he stole it off me! He said, "Oh yeah, I'm playing through that tonight!" I said, "What are you talking about? This is my new amp!" He pointed to his rental amp and said, "I'm not playing through that piece of ****." So he took mine! We went out onstage that night and Jaco got this huge wonderful busy sound and I played through this peanut. He was formidable! You can hear it in the mixes back then. He was very dominating. But I put up with it; I even got a kick out of it. Because I was so thrilled about the way he played. It was exactly what I was waiting for.
He was an innovator. First of all, he was changing the bottom end of the time, and he knew it. With that went a certain amount of confidence, which at its worst was offensive to some people. It didn't offend me....
I know he stretched me. I stretched him some too, inadvertently, on things like "Don Juan's Reckless Daughter."
