P.S. I'm seeing some "confirmation bias" in your response, too -- In your conversations with others, Jaco's name almost never comes up, and his name comes up rarely even when you talk with bassist. So then, it must be true that he's not very well known outside a very small group of bass players and '70s fusion fans. ... Not really a good measure, you know?
Well, then we get into the mechanics of trying to prove a negative (which kind of came up above).
In my case, it's not confirmation bias as such, because every time he does come up, that is evidence against my thesis that he isn't that well known in general, rather than evidence for it which would be confirmation. I'm noticing the contrary evidence and subjectively assessing about how often it occurs.
I mean, if the guy was really such an iconic musician to the general public, it does stand to reason that I would hear of him from time to time in random other situations, as I do many other musicians that I'm not personally into. Even though I play bass myself and know lots of other musicians, and like I said, Les Claypools' name comes up a lot more often.
Maybe I'm imperfectly assessing it or forgetting some of the times he has come up - certainly that's possible, and I don't know what I don't know, so I can't evaluate that. But that would be a different type of logical fallacy.
Either way people just generally tend to think that their experience and perspective is more valid or accurate than others, which on some level makes sense considering this is the only perspective they will ever be able to literally experience themselves.
That's a problem when this extends to making assumptions about what other people's experiences, influences, and cultural context must be as if they had the same background, values, and tastes as yourself.
To give you a broader example, I've been playing bass since '83. I make no attempt whatsoever to "keep up" with bass playing in and of itself. I do not care about what other bass players did hot solos that were written up in magazines for other bass players. I don't think the bass playing I love the most came from that kind of place, either.
I've got probably 7 or 8 thousand jazz records, and if I named for you my favorite musicians, or favorite writers or soloists or whatever, or if you spent as much time as you liked looking over my collection, based on that information alone you would absolutely not be able to tell that I am a bass player (or guitarist as I am as well).
The whole idea that you should identify yourself as a bassist in such a way that it changes your musical tastes and values, and that awareness of and an ongoing comparison to other bass players should affect how you play personally, is absolutely and completely not necessary to playing the bass, or playing the bass well.
Once you leave the bubble of people defining themselves that way you see how limiting and limited that bubble is. You can't see it when you're in it, and if you've never left it, you don't know that it's a box.
For me the goal is to have whatever is played be an un - self conscious essential part of the song. That might mean playing a part with few elements, or it might be a crazy performance, I don't really care so long as it is stylistically aware and appropriate and present, and not some self absorbed ego fest from a guy with some personal insecurity that wants to prove he can play but never seems to make the point to his satisfaction so that he can let it go.
I am absolutely comfortable with playing a simple part of no particular interest to bass players as such, or even using a flawed performance on a recording, if the overall music is good.
I even kind of enjoy the feeling of letting go of caring about my own part as if it was it's own thing in isolation- because it's not. There's only the music as a whole, and when you listen to the music as a whole and the bass player is drawing your attention away from the soling saxophonist who is perfectly competent and patiently waited until the right moment for his expression, it's not good. Anybody who isn't distracted or operating under pre conceived notions can easily see that. Sometimes a lot of stuff at once is cool but we all know when people are talking over each other instead of listening.
Just like I've told many intermediate/"good" drummers: the minute you stop trying to prove you can play is the minute you actually do start playing really well.
