i would suggest No Control and Suffer...this is when they formed the "bad religion" sound

.....but if you want more straight forward early 80's LA punk rock check out 80-85 which is a couple of eps and their first album 'How Could hell Be Any Worse'...in my opinion the best song they ever recorded is on 80-85 "Along The Way".....if you like these check out Against The Grain for super melodic hyper-intelligent punk rock.....
