The Middle Class, formed in 1977 in Santa Ana, California, are widely recognized as pioneers of the hardcore punk genre. Their 1978 debut EP, "Out of Vogue," is often cited as the first hardcore punk record, influencing countless bands with its rapid tempos and raw energy. The lineup featured Jeff Atta on vocals, Mike Atta on guitar, Mike Patton on bass, and Bruce Atta on drums. After releasing their sole LP, "Homeland," in 1982, the band disbanded but left an indelible mark on the punk scene. They reunited briefly from 2011 to 2014, until guitarist Mike Atta's passing in 2014. ([en.wikipedia.org](https://en.wikipedia.org/wiki/Middle_Class_%28band%29?utm_source=openai))
