victor wooten is amazing. I really think his brain has super powers as far as rhythmn goes. When i hear his stuff all I can say is wow. My personal favorite is scott reeder, nick olivaeri, stanley clark , geddy lee the above mentioned and flea.
geddy lee is really good. Who are the rest of these guys?
peanut butter google time!!!
Alot of the guys I metioned are underground . Nick olivarei was the queens of the stone age bassist for a while and is really good. Stanley clark is one of the best jazz bassist ever. Scott reeder is one of the best bassit youll never know.
