Happy Birthday to you! Congrats on scoring tickets to see Metallica. Hope the show is everything you hope it will be. They have been rockin' it for a long time now. I only have their Black album, but listen to many of their earlier and later tunes.

Enjoy the concert, and share a few pics and your review of the event after you get back.
