Former NIGHTWISH singer Tarja Turunen performed her new single, "I Walk Alone", last night (Friday, November 30) at the farewell fight of the German female boxing champion (and Doro Pesch's close friend) Regina Halmich. The event took place at the DM Arena in Karlsruhe, Germany.Tarja's performance (which was a playback) was broadcast on German TV and can be viewed below. Turunen's new solo album, "My Winter Storm", entered the German Media Control chart at position No. 3. The CD, which reportedly was certified gold in Finland for sales in excess of 15,000 copies on the day of the LP's release (November 14), landed on the Finnish chart at No. 1 and has since moved down to position No. 4. "I Walk Alone" entered the German single chart at position No. 16. "My Winter Storm" will be released in North America on February 26, 2008. The CD was produced by Daniel Presley (FAITH NO MORE, JEWEL, THE BREEDERS), who has been joined in the studio by a truly stellar line-up of musicians: Doug Wimbish on bass (LIVING COLOUR, ANNIE LENNOX, JOE SATRIANI, JEFF BECK, MADONNA, ROLLING STONES), Alex Scholpp on electric guitars (FARMER BOYS) and Earl Harvin on drums (SEAL, PET SHOP BOYS, AIR), a player personally selected by Tarja after she saw him stealing the show at a SEAL concert. Keyboards and programming, meanwhile, are being provided by Torsten Stenzel, whose previous credits include NELLY FURTADO, MOBY, TINA TURNER, VANESSA MAE and more.
