here are some of my picks Radiohead - Colin Greenwood is great! He does a great job of locking in with the drummer without staying on the root for the whole song. Tool - I'm not a big fan of their ideologies, but they really make some great music. Rush - Geddy Lee... as Homer Simpson would say: ggaaaaaaaarrrrrghhhhh. Smashing Pumpkins - D'arcy is a really good bassist with a hypnotic sort of feel. I wish they wouldn't turn her down so low in the mix... I didn't include some of the more obvious bands like Primus, simply because I'm a fan of the bassists, not the band. Now list yours.
