Bad Religion is an American band that plays punk rock music. They were created in Southern California in 1979 by Jay Bentley (bass), Greg Graffin (vocals), Brett Gurewitz (guitars) and Jay Ziskrout (drums). People think that they brought back punk rock and helped pop-punk bands during the late 1980s. Since they were created 30 years ago, Bad Religion has had a lot of members come and go. Greg Graffin is the only person that's been in the band the whole time but today there are three of the four members that were in the group when it started.
