The Proletariat are a punk rock band from Southeastern Massachusetts, whose heyday was during the 1980s, when they were active in the early Boston hardcore scene, sharing the bill with many of the best punk and hardcore punk acts of the time, despite their recorded output having a decidedly non-hardcore aesthetic; the Proletariat show more strongly the musical influences of early British post-punk bands such as Wire and the Gang of Four in their fractured guitar sound and Marxist-themed lyrics.

This Is Boston, Not L.A. is a hardcore punk compilation released in 1982. It is considered the definitive album from the Boston hardcore scene, as several of its most prominent bands appear on the record, namely, Jerry's Kids, the Proletariat, the Groinoids, the F.U.'s, Gang Green, Decadence, and the Freeze. For them, with the exception of the latter, This Is Boston, Not L.A. was also their debut release. Al Barile's band, SSD, were asked to contribute, but they refused to participate.
