Zephyrus
Tyrants and Slaves
Since no one mentioned Dimmu Borgir, I'd like to throw that one in. They're symphonic black metal, and easily one of the most accessible black metal bands. They're what got me into the genre.
Good albums of theirs to start with:
Enthrone Darkness Triumphant
Spiritual Black Dimensions
fixed.
PEM isn't a good introduction because it's way too overproduced and lacks many elements integral to black metal. SBD at least has atmosphere and simpler song structures.
