They honestly have one of the most insane stories of any punk or hardcore band. In fact, I'd put them right at the top. Off the top of my head, only Reagan Youth would rival it.
To summarize though, they come from a shitty part of Detroit. The original CAL vocalist was murdered by a friend of the band. The guitarist then stepped up on vocals for the majority of their career. At some point, substance abuse and disputes between members got the better of them and they broke up. One guitarist then died because of drug abuse. Another ODd on heroin. Then just a few years ago, the second vocalist went to prison for armed robbery. Just insane shit. There are stories of members shooting up crack houses, getting in fist fights on stage and pretty much just being violent wherever they went.
