[b]Is Rolling Stone gathering moss?[/b] By Mark Caro Tribune entertainment reporter No Prince, but, hey, they’ve got Stewart Brand! I just picked up the thick, snazzy The Fortieth Anniversary edition of Rolling Stone, a magazine I read religiously when it was closer to its 15th anniversary. To commemorate, the magazine conducted interviews with 20 “artists and leaders who helped shape our time.” And they are Bob Dylan, Jimmy Carter, Paul McCartney, Ringo Starr, Norman Mailer, Tom Wolfe, Bob Weir, Patti Smith, Steven Spielberg, Martin Scorsese, Jane Fonda, Jack Nicholson, Bill Moyers, George McGovern, Stewart Brand, Michael Moore, Mick Jagger, Keith Richards, Jackson Browne and Neil Young. I generally try to avoid the politics of representation, but this list makes Rolling Stone’s worldview appear rather, um, monochromatic.
