Original witchy woman Stevie Nicks made her mark with love songs ("Landslide," "Rhiannon") full of sweeping imagery and mystical elements to match her smoky voice. Clad in gauzy, sparkly layers, Nicks has always evinced a gypsy, libertine air. She benefited musically from her on-again, off-again creative relationship with Fleetwood Mac, which provided the crisp chops and surprising rock sinew that separated Nicks from fellow '70s balladeers. Rod Stewart still sports the same spiky coif and gruff, sexy rasp that made him an icon in the 1970s, and he has aged better than Mick Jagger. After decades as a rock frontman, Stewart has gone Vegas, churning out pop standards on a series of big-selling albums. His four American Songbook releases have revitalized his career and turned him into a latter-day Sinatra while earning him his first Grammy. Given their commercial success and history of romantic wreckage, can we agree that blonds do indeed have more fun?
