Wolves in the Throne Room

Bearers of the US black metal. You must check out their nature themed "Cascadian Black Metal" album, a wonderfully atmospheric album full of riff-o-rama. Another must listen is their album, "Celestial Lineage", dating back to 2011.

And how about "Celestite" released in 2014,  an instrumental ambient companion piece to Celestial Lineage, in which the atmosphere was at least as dark as the forests of Washington state, home base for the band. After a long three years break, the Wolves In The Throne Room trio has resurrected and are currently working on new material (their heaviest and darkest in some time) and are coming to Alcatraz.  Do not miss it as they'll put down a scorching set!
