Grafvolluth are black-metal craftsmen, creating complex, epic material that incorporates experimental music (they have shared membership with Kama Rupa; live video here) and progressive-rock arranging. The core of their songs stays very raw and dirty, though; no less "ugly" for the sophistication of its context.
Their latest full-length, Long Live Death! on Regimental Records (a longstanding  purveyor of vital black metal), is a My Castle of Quiet favorite, equal parts rough-hewn and contemplative/spiritual, like some beautiful, old-Teuton carving.
Grafvolluth rarely play live, maybe never on the radio, so their LIVE appearance on MCoQ is truly an event "against time." Don't miss it!
