Hexvessel - "Invocation Summoning" from stereogum on Vimeo.

Check out Hexvessel´s "Invocation summoning" from the album "Dawnbearer" (Svart Records 2011). I know nothing about these people, but according to Stereogum  this is a solo project by Kvohst from the bands Dødheimsgard and Code. Crustcake claim Kvohst and Aort, who also plays in Code, is Hexvessel.
 The music is a strange mix of psychedelia, prog rock, Canterbury and folk, and if you have access to Spotify, the whole album is streamed there.
