Brockie stated he grew up a "rocker"; he started out listening to heavy metal as a kid, then immediately became more absorbed into punk rock as a teenager, especially the 1980s hardcore punk scene. Brockie stated his favorite punk bands were Bad Brains, Black Flag, Dayglo Abortions and Charged GBH. He got back into heavy metal when thrash metal bands, such as Metallica and Slayer began to emerge.
