Rapper, rocker and country crooner Kid Rock matches a knack for pop reinvention with a blue-collar swagger reflective of his Motor City roots. Cutting his teeth in the Midwest hip-hop circuit, he blew up with 1998's Devil Without a Cause—a rap-metal crossover packed with rebellious rhymes, funky riffs and rolling beats slathered in axle grease. While Rock certainly excels at playing the cocky outlaw, several of his most memorable tunes, including the classic rock anthem “All Summer Long” and the Nashville-tinged “Born Free”, show off his gift for tender, heartland soulfulness.
