Avril Lavigne

Avril Lavigne first appeared in summer 2002, touting an addictive debut single (the spunky pop/rock gem "Complicated") and a skatepunk image that purposely clashed with the polished glamour of mainstream pop. Lavigne, who was 17 at the time, quickly rose to teen idol status, selling several million copies of her debut album, Let Go (the best-selling album by a female artist in 2002), while inspiring a genuine fashion craze with her penchant for tank tops and neckties. As the decade progressed, so did Lavigne's marketable sound, which took a contemplative turn on the sophomore effort Under My Skin before reaching an aggressively upbeat tone for 2007's The Best Damn Thing.
