If nothing else, rock ‘n roll has always been about rebellion. Elvis, the Stones, the Ramones, Patti Smith and Nirvana never conformed with mainstream society. Rock ‘n roll is the ultimate anti-establish art form — dangerous, daring, angry, sexy, bombastic. So it’s easy to see why this year’s Rock ‘n Roll Hall of Fame class induced snide comments from the rock literati. You’re more likely to hear Deep Purple, Chicago and Steve Miller in a doctor’s office or minivan as a dive bar these days. Ironic that the inductee with the most street credibility this year entered the Hall through the side door, hip-hop still being dismissed in some circles of traditionalists. But as Ice Cube said, “Rock ‘n roll is not an instrument; it’s not even a style of music. Rock ‘n roll is a spirit.” Listen to this — or something by Johnny Cash or Miles Davis or George Clinton — and tell me it’s not rock ‘n roll.
