The 68-year-old rock 'n' roll legend Stevie Nicks is currently on tour again, making a stop at Madison Square Garden tonight. She's been a presence on the stage since the early '70s, when she was the lead singer and only female member of Fleetwood Mac. In 1981, she began her successful solo career, and has since become not only a musical icon, but also a fashion and beauty inspiration, with her free-flowing shawls, amazing '80s curly bangs, and overall empowering aura. In short, Stevie Nicks goes her own way. Here, a closer look at her unrivaled rock 'n' roll hairstyles through the years.
