The band was formed in 1977 and was a contemporary of the bands featured in The Decline of Western Civilization. Their songs reflected the anger and angst of growing up Chicano, and this was reflected in their sardonic hi-speed version of Ritchie Valens' "La Bamba". The Plugz are generally acknowledged as being the first D.I.Y. punk band in L.A., having started their own PLUGZ RECORDS and later Fatima records.
The Plugz also feature prominently on the soundtrack to the movie Repo Man. They composed original instrumental music for the film, and performed "Hombre Secreto," a Spanish version of Johnny Rivers' "Secret Agent Man".
The Plugz accompanied Bob Dylan on his appearance on "Late Night With David Letterman" on 22 March 1984 for three songs: "Don't Start Me Talkin'" (by Sonny Boy Williamson), "Jokerman", and "Licence to Kill".
The Plugz reunited the three founding members for The Masque 30th Anniversary Party and Book Release show on November 11, 2007 at The Echoplex in the Echo Park district of Los Angeles, California.
