More recommendations no-one will take up.
Burzum The name means 'Darkness'. You will find no more powerful statement of intent and purpose in any band name ever. Burzum is the be all and end all of minimalist music, mixing sparse, hypnotic keyboard compositions with writhing, rhythmic, bleak and wasted black metal to create an over-powering aura of spiritual darkness. To really get Burzum, you have to listen to it on an album by album basis, preferably in the original format (LP or CD) or approximation thereof. Each Burzum album is designed to put it's listener into a psychological mood-state: almost a spiritual experience. Forget what Varg Vikernes did, or what he said. Just fucking listen.
Recommended tracks: If you're GOING to sample tracks, 'Ea, Lord of The Depths', 'Beholding the Daughter of the Firmament' ('Erblicket De Tochter Des Firmaments'), 'The Crying Orc', 'Han Som Reiste' and 'Die Kraft de Mitgefuehls' ('The Power of Empathy'). But as I said, albums are really necessary. For people here, I'd recommend the purely electronic works 'Daudi Baldrs' and 'Hlidskjalf'. But it's all incredible.
And now, LISTEN UP, because here's pretty much the two Indie bands I like:
British Sea Power Powerful, atmospheric experimental rock music miles above most of the other stuff I've heard from the genre. I particularly recommend the album 'The Decline of British Sea Power', and my favourite track by them 'Fear of Drowning'.
Tan-Hauser Gate Small, local and probably quite hard to get hold of, I think there may be another band with the same name as well, but they're wonderful. Only released a self-titled demo. Subdued, keyboard driven hypnotic rock music with a liberal dash of goth and the same oceanic mood that draws me to British Sea Power. 'Not Today' is one of the songs irrepressibly associated with my home Island, in my mind.
