Since the 1990s, various forms of popular music have become associated with values few could have foreseen decades earlier: militarism, misogyny, nativism, and outright racism. Historic changes in geopolitics, economics, technology, and culture have redefined rock’s assumed role as the soundtrack of rebellion and dissent. As acts both progressive (Rage Against the Machine, Pearl Jam, Green Day) and regressive (Guns n’ Roses, a revived Lynyrd Skynyrd, and the indestructible Ted Nugent) win fans, and as white rappers like Eminem and Kid Rock have upset old stereotypes, it is clear that rock ‘n’ roll has changed as much as its consumers have.
