...I hear ya...I am 48 and understand oldschool...the problem that I have with what you are saying is that you judge the new as if it is something other than evolution!....listen back to stanley clark ans others at that time way back when....they were doing all of these things in jazz.....it has just moved to gospel....back then there was a place for the pedal tone and a place to solo....
I think we must learn to respect the evolution of an art...though we should remember that everything isnt for everyone.....
dont forget the projects that you describe by these bassist are not accidents or bad performances but were designed to be what the artist wanted....
I see the place for all of it!...our job is to play appropriately for the forum we are in.
