Norwegian black metallers GORGOROTH have been confirmed for the Hammerslag Festival, set to take place July 20 at Støperiet in Tønsberg, Norway.For more information, visit www.hammerslagfestival.net. As previously reported, GORGOROTH guitarist Infernus was recently released on parole after serving time for aggravated sexual assault in connection with an alleged rape of a 29-year-old woman in Bergen, Norway in 2004. Infernus (real name: Roger Tiegs) and a friend (whose identity has not been revealed by the Norwegian media) were found guilty in 2005 of raping the woman. They were both sentenced to three years in prison. In January 2006, the court of appeals upheld Tiegs' friend's rape conviction, but found no evidence to support the rape charge against the GORGOROTH guitarist.

GORGOROTH's most recent album, "Ad Majorem Sathanas Gloriam", was released last year via Sweden's Regain Records. The band was previously signed to Nuclear Blast Records, who released three CDs from the group: "Twilight of the Idols" (2003), "Incipit Satan" (2000) and "Destroyer" (1998).
