These Mohawk wearing "Oi" punks saw their debut manifest as a violent EP Leather, Bristles, Studs, And Acne (1981). Their brutal three-chord attack would continue on to give them a 17 US with their debut album Baby Attacked By Rats (1982). This, it would turn out, was their only hit for they were forced aside by the prevailing NWOBHM and speed metal movements and so after shortening their name to just GBH and releasing Midnight Madness and Beyond (1986), No Need To Panic (1987), A Fridge Too Far (1989) and From Here To Reality (1990), GBH gradually switched to a decidedly more metallic/speed metal approach with Church of the Truly Warped (1992) featuring Joseph "Fish" Montanaro on drums who would only occupy the role for 2 years before Scott Preece assumed the role.
Their speed metal transformation experiment didn't last very long and by the time Kai Reder replaced Williams, they had reverted back to their UK82 style for the release of Punk Junkies (1996), Ha Ha (2002), Cruel and Unusual (2004), Perfume and Piss (2010) and Momentum (2017).
