Riding the wave of teen pop stars that emerged in the late ‘90s, Christian Aguilera has remained one of the most talented performers, turning out a variety of amazing albums where she shows off her sexy voice and songwriting. Known at times as Xtina, she’s reinvented her image a few times, going from innocent girl-next-door to sultry lust queen to classic, vampy pop diva. Fans have followed her transitions, eagerly anticipating what the next bold move will bring from Christina.Christina Aguilera got her start as a young girl, appearing on Star Search and joining The New Mickey Mouse Club as a teen. In 1998, she recorded a song for the Disney children’s musical, Mulan, which gained her considerable attention and helped her ink a record deal. Just a year later, a self-titled debut became a huge hit, with “Genie in a Bottle” and “What a Girl Wants” establishing her as an amazing vocalist who could tap into the emotions of her listeners.The album was a massive hit, and Aguilera followed it up the next year with a Spanish-language album, Mi Reflejo. A Christmas album, My Kind of Christmas, came afterward.It wasn’t until 2002 that Christina made a big splash again, reinventing herself as Xtina for her second full-length, the sex-saturated Stripped. With body piercings and revealing outfits, she seemed to have grown up very fast between her two full-lengths. Songs like “Dirrty” showed this off the most, and many of the lyrics surpassed any of the sexy teasing that she exhibited on her debut.In 2006, though, Aguilera released Back to Basics, a title that suggested she wasn’t recanting the embrace of her sexuality on the last album, but didn’t need to flaunt it as prominently. Back to Basics instead offered up an image of a Bettie Page pin-up, with gorgeous, flowing hair. Aguilera has become the classy diva she always was—and delivered some great songs in the process. “Back in the Day” and “Mercy on Me” are just two of the album’s songs that show off the newfound grace and voice of this fabulous artist.
