Did no one say Between the Buried and Me??? The bassist is INCREDIBLE! skip to 1:00 if you only want to hear the bass part. That song just happens to be a full bass solo but their "normal" songs have phenomenal bass lines too. If you don't have them already (but if you're into bass then you probably do) then get Les Claypool's solo albums. He's made a bunch under a bunch of different names. I'd recommend of Whales and Woe. He's an amazing bassist. He was rejected from Metallica for being too good hahaha.
