Defunct Norwegian black metallers WINDIR have pushed back the projected release date of their posthumous DVD, "Sognametal", to April/May from the previously announced February. The delay is being attributed to "technical problems with the printing" of the DVD, according to a posting on the group's web site.As previously reported, the "Sognametal" DVD features the complete WINDIR concert from September 3, 2004. The show, which was staged as a tribute to WINDIR frontman and founder Valfar (who died in January 2004), featured WINDIR guitarist Sture on most of the vocals, as well as guest vocals by Cosmocrator (MINDGRINDER) and Valfar's brother Vegard. Also included on the DVD are WINDIR live clips from Gaupne (1996), Sogndal (2001 and 2002) and the Inferno Festival in Oslo 2002, plus backstage material, an interview with Valfar from Norwegian national TV, and a photo gallery. VREID guitarist Ese produced the DVD at Hváll's Studio 1184 last fall.
