What this thread needs more of...
I actually totally agree. While I love to study the flashy guys (most of the people I mentioned in my earlier posts) from a technique standpoint, most of my playing revolves around more pocket and countermelody as opposed to soloing and flash in the pan stuff.
The problem is most people don't remember the pocket players, so they can't add stuff in a chat like this. Personally, I feel a lot of people consider "pocket players" people who play the same lick over and over again, reliably. While theres definitely a time for that, I personally think that a truly good bassist is someone who can add a little (read: very little) flair to his playing in order to emphasize certain passages, and yet stay out of the way and make the other musicians sound great.
I mentioned Stefan Lessard, hes an excellent example of this. People think of tunes like "Crush" where he has a leading part, but if you dive into a lot of DMB tunes, he holds it down really well, while still adding his own style to the song. With that many "up front" players (Boyd, Jeff, Tim at the very least, and sometimes Dave...not to mention carter pretty much constantly), he gets lost in the mix a lot.
Another one that is a great technical player but typically plays a much more supporting role in his gigging is Anthony Wellington (really nice guy too). Check out his work with the Victor Wooten band. Hes a very strong believer of "Making Victor sound good", and he does it really well.
I'd also put Michael League, leader of Snarky Puppy, in that group. If you're into Jazz/Big Band stuff at all, check out Snarky Puppy. Actually, they cover such a range of styles that everyone should give it a look. From a performance standpoint, League doesn't do too much. But he also composes almost every song from SP, and definitely helps direct things (which is important when you're band is like...30 people who rarely practice together).
