You guys need to learn what music is about, its about ENTERTAINMENT. Todays word for that might be FUN. Sorry but I would rather see a FUN band play the same pattern on everysong, with a bass player who plays the root note and a drummer banging away at the snare every quarter note than see [Insert World Known Bassist's name here] bang 128th notes on 4 strings. How exciting? NO.
See the point of music is entertainment, they are entertaining the masses which are most likely not musicians. Therefor they are musicians relating to NONMUSICIANS. They are also playing for a more younger audience which also means High energy.
Now [World Known Bassist] is going to play his concert. Well he is probably going to be targeting another audience, probably other musicians who can relate to his song about him and his bass guitar, whereas the other group could care less.
Now one of the reasons we get so much punk bassist bashing is because while we waste hundreds of hours plucking away in a little room listening to bass solos and spending all day on talk bass wondering how we can improve our technique and which degree our thumb should be tilted inorder to slap properly. They are out there PLAYING there basses like this

ENTERTAINING and enjoying them selfs.
They could give a crap about weather there bass is made out of mahogany or walnut. They grap the easiest bass to find, [precision] grab a pick [because they see the guitarist has one] and grabs the biggest loudest thing they can find [8x10] and they ROCK OUT because there musicians there to entertain the masses [nonmusicians] so they try to relate to them.
I do not mean to offend any other more advanced bassist out there, I too consider myself MUCH better than your average famous bass player. However there out there playing while im here on a bass forum trying to figure out how to get that perfect tone and learn how to play victors songs.
All that Im trying to say is that you guys need to give them a break, there famous and suck your not and good get over it!
