Windir will be playing one last special farewell concert on September 3 at the Rockefeller Arena in Oslo, Norway in commemoration of frontman Terje "Valfar" Bakken who tragically passed away in January. The date not only marks what would've been Terje's 26th birthday, but is also the release date for the band's 2xCD retrospective "Sognariket". As mentioned before, all proceeds from sales of that album go directly to Terje's family. Other bands paying tribute on the show are Enslaved, Finntroll and Mindgrinder.
