Angrier and less pretentious than the drug-addled punk and new wave music genres, hardcore was an underground tribal movement created with passion but ultimately destroyed by infighting and dissonance. Among the important figures who emerged from hardcore are Henry Rollins, Dave Grohl (of Nirvana and Foo Fighters), Ian MacKaye (of Fugazi), and the Beastie Boys. Hardcore's legacy, however, continues to influence the do-it-yourself anticommercial trend of independent record labels and touring networks. The author experienced hardcore firsthand as a promoter, record label owner, and radio DJ, and he intersperses the book's oral histories with his informed commentary. Also included are photographs, discographies, and a complete national perspective on the genre.
