Enslaved

When we last heard from Enslaved, they were pushing forward with their blend of progressive and black metal, making a mixture of sounds that shouldn't work together sound unlike anything else.

The downfall of extreme metal is the overemphasis on the word 'extreme'. So often, bands become obsess with making sure their music is extreme, which ends up taking it so far away from the core of songwriting that little is left but a shell of noise.
