I've been looking around, but the only good ones I've found are 1349 and Cradle of Filth. If anyone has some suggestions, please post. Also, avoid listing Melodic or Symphonic black metal bands, I'm after the normal stuff.
Definitely check out Mayhem and Burzum. The first Black Metal band I actually listened to was DarkThrone, they were good but then I found Mayhem and they rock! Make sure you get De Mysteriis Dom Sathanas though, thats their first album and their best one at that.
As for Burzum, I own everything from Burzum. I own all of his albums and 3 bootlegs.
More bands:
Keep Of Kalessin
Belphegor
Diabolical Masquerade (Black Metal mixed with Death Metal, its like half and half)
Hmm, thats all I got. I haven't listened to Black Metal in quite a bit, I have been into a lot of Melodic and Technical bands recently.
