During the late '60s and early '70s, Detroit was home to not just Motown, but a thriving rock & roll scene that had a major impact on mainstream hard rock of the '70s, and also laid much of the initial groundwork for the punk movement. Detroit rock was simple, hard-driving, and ultra-high-energy; it was also often raw and grimy, prizing attitude far above polish. The roots of Detroit rock actually extended out to two nearby cities: the industrial Flint and the college town of Ann Arbor, though the most important performance venues (including the Grande Ballroom) were in Detroit itself.
