But, to suggest that guys like Lang, Donati, Berlin, et al are not making positive or significant contributions simply because they aren't recording with Stevie Wonder or don't have Vinnie's discography is wrong - IMHO
Fair enough.
I see things a little differently. It's OK to agree to disagree I think.

I get a little testy when excellent artists are criticized and popularity or commercial success is an underlying reason.
I'm not aware I've criticised them, not even Berlin. I dispute some of the things
others say about them. I'm happy for Donati and Berlin to ply their trade in which ever way they see fit. It doesn't mean I have to agree they've been a 'huge influence'.
Trying to get back on track......
It may well be that Jeff Berlin has raised the bar for bass players.
You could argue the same for Gavin Harrison, Donati etc....
I merely tried to point out that raising the bar for a small niche area of musicians might be less world shattering than was being proposed.
Miles Davis 'raised the bar', was capable of technical brilliance and was very popular.
He could also play one heart wrenching note per bar.
My benchmark for raising the bar can be technical, but must also move me.
If it moves a lot of other people too, all the better.
It really has absolutely nothing to do with selling CD's.
