Bruce Corbitt, frontman for Warbeast, has spent the last 35 years perfecting his dark vocal art. Influenced by Iron Maiden vocalist Bruce Dickinson and many others, Corbitt evokes a similar power, the kind that causes heads to bang. He first unleashed it as the frontman for speed metal band Rigor Mortis in the '80s with the late legendary speed metal guitarist Mike Scaccia by his side. A year after he joined the band, it signed with Capitol Records and released its self-titled debut album. Some called the group "the next Metallica," but Corbitt doesn't sound like James Hetfield. Instead, he assaults the microphone with his unique sound — one part demonic, two parts monstrous — as he unleashes lyrics such as "the fragrance of the corpse is the stench of his kin" on fans who seem to devour his music in the mosh pit.
