I watched a documentary on the making of Metallica's self-titled 1991 album (also known as "The Black Album") the other night. It was informative, but one thing struck me:
Jason Newsted and Kirk Hammett are complete nerds.
Actually, I knew this about Hammett already--I've seen him in interviews. If you haven't, you should. His voice and mannerisms skew towards the effeminate. So while he may be a fire-breathing he-god (whose heart pumps not blood, but pure liquid awesome) when he has a guitar in his hands, as soon as he puts it down and says something you start thinking "oh, I could so take him in a fight."
Newstead, instead, just comes off as nerdy. And it's the same deal, watch him play bass and he is the monster of a man projecting thundering tones through his 5-string uber-guitar, until he sits down to just talk.
I understand that the socially awkward gravitate towards music. And I realize that musicians are nothing like the version of themselves that they embody when on stage. I'm just not used to it being quite so drastic. At least Brian Warner (a.k.a. Marilyn Manson) can talk a good game.
Of course, he's also the front mane.
