In a somewhat surprising move, Anvil bassist Glenn Five (real name: Glenn Gyorffy) has announced that he’s leaving the band after 15 years over creative differences. It’s somewhat surprising because the Canadian trio are arguably more popular than they’ve ever been as a result of the 2008 documentary Anvil: The Story of Anvil. While Five took a backseat in the film to the relationship between original members Steve “Lips” Kudlow and Robb Reiner, the film not only fueled Anvil’s comeback among metalheads, but made them popular among people that weren’t even metal fans. “Although Anvil has been a great band to play in, I have been limited creatively,” Five said in a statement picked up by the Hollywood Reporter. “I have a wide taste in music and I feel that it’s time to broaden my horizons.” Glenn joined the band in 1996 and played on six albums, most recently last year’s Juggernaut of Justice. The band hasn’t named a replacement yet, but are due to kick off a U.S. tour later this month. Suffice it to say that whatever new project Glenn lines up probably won’t have an award-winning documentary made about it that fuels a renaissance.
