If you are going to black metal, I urge you to stay away from Dimmu Borgir. I mean to pick up a CD look at their album titles and song titles, then you get to listen to a polished black metal CD.
I also recommend Megadeth's Rust In Peace, a solid thrash metal album, with some of amazing solo's between Mustaine and Freedman.
For vintage, get Sad Wings of Destiny by Judas Priest, probably their best album released.
