Norwegian black metallers WINDIR have announced plans to perform on final concert as a tribute to late frontman Terje "Valfar" Bakken, who tragically passed away in January. The concert, dubbed "Heidra Valfar", will take place on Friday, September 3 at the Rockefeller Arena in Oslo, Norway.

"The 3rd of September would have been Valfar's 26th birthday, and we would like to honour his memory by doing one last show," the band said in a statement. "Sture will be doing most of the WINDIR vocals. We are also glad to announce that 3 bands will be joining us this night. ENSLAVED, FINNTROLL and MINDGRINDER will be doing shows in honour of Valfar. The 3rd of September will also be the release date of the last WINDIR album, out on Tabu Recordings."

Tickets for the "Heidra Valfar" concert can be purchased at www.billettservice.no beginning on Saturday, March 27.

As previously reported, WINDIR's forthcoming CD will be a two-disc set. The first CD will include new material, unreleased material, tribute songs from other bands and live tracks, while the second CD will be a compilation of the music made by Valfar. It will include tracks from the first demo, "Sognariket", to the last album, "Likferd". All proceeds from this CD will go directly to Valfar's family.
