I'mma recommend two younger fellas: Erlend Caspersen (currently in Spawn of Possession) and Nick Schendzielos (currently in Cephalic Carnage, and yes, I did have to look up how to spell his name). They both have Youtube channels where they upload videos of themselves making me feel inadequate: Bajskung for Erlend (Poopking in Norwegian (and before you judge him for that, Devin Townsend's channel is Poopy Nuggeteer)) and BassForDays for Nick. I'd check both of them out!
And a generic list of bassists whom I admire and/or have inspired me: Jason Newsted (got me playing bass in my teen years), Nefarious from Macabre, Bill Laswell from Praxis, Alex Webster from Cannibal Corpse (also a superhumanly nice person), Eric Langlois from Cryptopsy, Sean Malone from Cynic, Jonas Hellborg from 4,000 different projects, Dick Lövgren from Meshuggah, Charles Mingus from his own band and Tony Choy from Atheist.
Also, I'm a bassist. You're all entirely free to call me great.
