London singer Amy Winehouse was initially marked as a neo-jazz diva. Although the tag may have been beneficial in terms of press coverage, it was misleading; unlike the inoffensive Katie Melua and Joss Stone, Winehouse had no fear of displaying the seamier side of her life. Her debut album, the aptly titled FRANK, was a solid collection of jazz-inflected pop, but it was the 2006 follow-up, BACK TO BLACK, that really set her apart. Displaying the marked influence of 1960s soul music, girl groups, and Motown, the album also boasted clever, sexually explicit lyrics and punchy pop arrangements, all pulled together by Winehouse's powerful vocals. Her hit "Rehab" became something of a personal theme song, as the singer became a permanent fixture in the tabloids, due to her wild behavior and infamous live shows.
