Formed in Birmingham, England back in the late 1970s, punk band GBH's brutal yet melodic songs, like the memorable "Sick Boy" and "City Babies Attacked By Rats," proved highly influential on future members of Metallica, Queens of the Stone Age, Nirvana, Rancid and many other bands. They still enjoy a devoted following in the UK, along with the rest of Europe, the United States and Japan, and now you can see these punk pioneers at Rex Theater in Pittsburgh, with opening acts The Casualties and The Cheats.
