if you mean influential on kids wanting to pick up instruments, then, yeah, I'd agree.
(add): But by influential I mean having a big musical impact.
Man I can't even get ready for this...I have to wonder if you slept through the 80's and 90's? They may not have had a big musical impact on you, but they undoubtedly had a HUGE musical impact on the hard rock and heavy metal community...now this may not have been YOUR cup 'o tea, but that doesn't change the fact that many musicians were influenced by them, their music, their playing (yeah I said it), and their show. As for your comment about him not being a great bass player....again, your opinion...
