Kick Ass Melodic Mosh Pit’n Metal! Core Zero is a Denver based metal/hard rock band that was originally formed in 2005 under a different name. Upon release of it’s first full length professionally produced album Doxology, Core Zero adopted their current name. The music can be described as melodic vocals, soaring solos, heavy guitars, and a tight rhythm section. If Disturbed, Avenged Sevenfold, Godsmack, and Drowning Pool had a four headed love child it would be Core Zero!
