Dormitory Core: A History Lesson in Under 150 Words. This genre of lush, melodic indie rock came into cultural prominence during the first decade of the third millennium as a response to noise constraints imposed on college students in close communal living quarters. Dormitory Core songs are often produced largely within the popular ProTools recording software by adolescent males locked in the throes of woe that accompany a failed coupling attempt. Largely composed within a closed-circuit system and often relying on headphones, Dormitory Core music produces a bare minimum of irksome racket, resulting in a harmonious relationship with neighbors. Musical influences commonly include Pet Sounds–era Beach Boys and Song Cycle–era Van Dyke Parks. Experts generally agree that composer Jim O’Rourke unintentionally invented Dormitory Core on his 1999 record Eureka by asserting that Americana was, indeed, “cool.” Notable artists within the genre include Brooklyn’s Grizzly Bear, which performs with TV on the Radio at 10 p.m. at the 9:30 Club, 815 V St. NW. $20.
