Speaking as someone who listens to bass first in music and who's transcribed most of Mendez's best basslines, there's never been anything on any opeth album to suggest he can play anything near as fast and complex as myung quite regularly does. I don't doubt he could play quite a bit faster if he wanted, but I do doubt very much that he could pull off some of the stuff Myung does, to speak nothing of some of myung's other bass-related talents like his pretty considerable abilities on chapman stick. I'm speaking in terms of technical ability alone here, don't give me some DREAM THEATER SUX U FGT BAS PLAYR IZ BETRU CUZ OEPHT RULEZ AND WANKIN DROOLZ!!~! PEAC EOUT! response like I'm sure I'll receive : Just the sad facts here.
