Looks like my faves have all been said. Nick Oliveri, Les Claypool and Jeordie White.
But here's a couple more I love for just showing that the bass can be noisey and and have the **** beaten out of it too. Jesse Keeler (Death From Above 1979) & Brian Gibson (Lightning Bolt).
Jessie Keeler... Death From Above 1979 Nick Oliveri - you know! Les Claypool - Primus Justin Chancellor- Tool Peter Hook - New Order Flea - RHCP & Bootsy Coillins - James Brown Band/Funkadelic
