It is easy to miss. They don't sing in Spanish or have obvious references. Being labeled as ethnic would probably have hurt sales, but that is also a shame. There can be room for anyone in any genre, and it might help if it were more obvious that inroads have already been made. I found them in a list of bands with Latinx roots in Celia C. Pérez's The First Rule of Punk.
For West Coast punk history, they are still important. According to NME, the police breaking up a Zeros show in 1979 heralded the arrival of punk riots to the US (something already familiar in Britain by then). It was The Zeros who played "Beat Your Heart Out" eight times in a row, and no other songs. That seems like the more obnoxious part of punk, but that is also a pretty good song. It could still have been a really good show.
Know your punk history.

We have a new 7" single coming out on Munster records. We toured Europe earlier this year. We will be playing with the Adolescents on December 6th in orange county. Etc. We will be recording more in October.Because of this, I am erasing the paragraph that indicated that they were not currently together. They clearly are. Orange County fans should check out the Garden Amp schedule. Tickets appear to be available through Ticket Web and Event Brite:
