How can we take the instrument where it's going if you don't know where it's been? An example from my own experience is that I started tapping at 16, before I saw anyone else do it. I thought I was the man, that I was gonna change the world with my new technique. I was 16 in 1994, so Victor Wooten, Stu Hamm, Billy Sheehan and countless others had been doing it for years, much better than me. I have been humbled ever since.
As far as the Jaco thing, i'm sure lots of us here can play his grooves, but the fact remains, he created them. His music endures. IMHO, "Used to be a Cha Cha" is the best solo he ever recorded. And that was off the top of his head, amazing!
That's my favourite jaco solo as well I recon.
