I consider myself a pretty lucky Metallica fan, in the sense that the Black album and Load were my introductions to the band and while I'm sure I heard "One" and "Master Of Puppets" before then, I didn't have any identity attached to the band, I just knew I dug the tunes. Even when I started going back and getting into their earlier stuff, it was all just a bunch of songs that I really dug.
I'll go see them anytime I get the chance. I've only seen them once, on the Death Magnetic tour in Boston, but the energy in the room was really, really cool and was definitely part of my experience. Their production is always killer and being a fan of pretty much everything but St. Anger ("All Within My Hands" is a cool tune) I know I'll get a whole night of what I consider killer tunes.
