Hadley Rock City

"Hadley Rock City" is a nickname given to Hadley, Massachusetts in the late 2010s. The name is a play on the song "Detroit Rock City" by Kiss. It was initially meant to be sarcastic, considering Hadley is neither a city nor widely recognized for it's rock scene. However, some feel that the name is appropriate due to Hadley's dominance of the underground indie scene in Western Massachusetts.

"Yo lets get a 30 rack of Narragansett and go see Pearl Sugar and Taxidermists at the Asbestos Farm tomorrow! You're gonna lose your mind in Hadley Rock City!!!!"
