text: Cleveland is the birthplace of rock and roll, but with the city's airwaves dominated by moldering classic rock stations that only toyed with modernity for the last several years, it also threatened to be the place where rock and roll lay down and died. Xtreme Radio has helped change all this by bringing a younger, hipper presence to Cleveland rock radio, and results have been impressive. The station has already thrown a pair of successful concerts that featured Blink-182, Rob Zombie, Static-X, and dozens of others, and it's reestablishing Cleveland as a primary market for modern rock.
