Metal, Hardcore, Indie, Rock
During the Louder Than Life festival, Robb Flynn, the leader of Machine Head, joined German power metal band Powerwolf on stage to share vocals with Karsten “Attila Dorn” Brill. As reported from MetalSucks, in that instant, the worlds of power metal, which is nearly operatic, and heavy metal, which is more conventional, combined to create something unique for the fans. All of this took place while the band is touring North America with DragonForce.
