According to a posting on NIGHTWISH's official web site, the band's "End of an Era" DVD and CD was certified gold in Finland on day after its release. The DVD has sold 9,000 copies so far and the double live CD has shifted over 15,000 copies.As previously reported, audio and video clips from "End of an Era", have been posted online at MusicBay.se. Due out in Germany today (June 2), "End of an Era" contains recordings/footage of NIGHTWISH's final concert with singer Tarja Turunen, which took place on October 21, 2005 at the Hartwall arena in Helsinki, Finland. In addition to the live footage, the DVD includes a slideshow of pictures from the Hartwall show and a 55-minute documentary, "A Day Before Tomorrow", featuring behind-the-scenes footage of the band in the 15 days prior to the Hartwall Show. The documentary was edited by Timo Halo, who also edited and directed the "From Wishes To Eternity - Deleted Scenes" and "End of Innocence" movies that were released on previous NIGHTWISH DVDs. NIGHTWISH fired Turunen via an "open letter," which was given to the singer immediately following the Helsinki show. The group are currently seeking a replacement vocalist before entering the studio in September 2006 to begin recording the follow-up to 2004's "Once", tentatively due in mid-2007.
