My single favourite black metal band is Burzum. Precisely because they are anything but the usual old school Norwegian black metal silliness. Well, musically. I guess in acts they were the very centre of all things stupid and church burning & murder specifically. But musically they were so far ahead of their contemporaries. The biggest tragedy of Varg murdering Øystein wasn't the death of somebody, it was us being deprived of a proper follow up to Filosofem, the single best metal record of the 1990s. Big statement, I know
It's a bit annoying really because I have named all the songs in Norwegian, but most folk know them as the German names, so everyone else knows that song as Dunkelheit but I know it as Burzum, and that's what the official Burzum website is the "official" title, coz you know, Vikernes is Norwegian and has always written in Norwegian, or at least mostly.
Anyway, love black metal. Bathory, Mayhem (up to a point), Darkthrone (especially their most recent stuff which is just damn good fun), Enslaved, Emperor (good God they are so good live!), Aura Noir, alot of the depressive bands like Shining, Lifelover, Bethlehem & Forgotten Tomb, & then alot of the better current black metal is American, folk like Woves In The Throne Room, Leviathan, Xasthur, Agalloch, Cobalt & Woods Of Ypres (OK, Canadian). There are quite alot of bland & uninspiring black metal bands, but there's also so many goodies in there that as far as metal goes it's probably the most rewarding sub-genre.
