Vreid covering Windir, a bit of a roundabout cover as everybody apart from the singer was the old and defunct band anyways.
The dead guys brother is 'singing' on this one, very weak, but the guitar work turns around mid song and is some of the most beautiful I have ever heard, ending in the old 2nd voice chiming in.
Song is 'Journey to the End' by Windir:
Six Feet Under - Piranha (Exodus Cover)
