Formed in 2011 under the working title Gary Busey Amber Alert (GBAA), ALTERBEAST combines the teachings of The Black Dahlia Murder, Necrophagist and Spawn of Possession with the classic death metal mastery of band’s like Dissection and Morbid Angel into an irate expulsion of sonic deviance. Their debut album, "Immortal", will be released via Unique Leader Records 3/18/2014.
