man.. no offence.. Geddy Lee is great and all, but either i havnt listened to enough of him or i'm just missing something... IMO he is over rated... (no ofeence to you bizzillion Geddy fans, just my opinion).. Les Claypool obviously ripps and IMO is one of the true best.. deffinately, Cliff rocks, orion pretty much ripps it up... not very difficult but alot of feeling and soul...
i think anyone who classifies RHCP and Nirvana together are in need of a visit to the doctor.. i have been listening to RHCP since i was about 10 years old.. they may be perceived as whatever now, but us who have been listening to them since the begining (or close to) know they are nothing like Nirvana...
my favorite bass player is Flea, i am forever figuring out his grooves.. i can listen to the same song forever and still hear new things.. still be amazed and still get goosebumps.. i never get bored with what he plays... he makes even the most simple songs sound incredible.. RHCP or no RHCP, Flea rocks..
there are many many others, i'll post later, i just had to get a bit of whatever out of my system (that Nirvana comment disturbed me)...
hope i didnt offend anyone, all just my opinion as is yours
cheers.
