After her fourth album, Stripped, appeared on this illustrious list I assumed no further Aguilera albums would be included; and if there was to be only one I was surprised it wasn't Back To Basics. Well, here that album also is, which, whilst unnecessarily long, is, nevertheless an excellent pop record and likely her best. On Side A Aguilera brings street cred from the likes of DJ Premier - whose beat on Ain't No Other Man gets even the usually snobby B-Boys and Girls up on their feet - whilst Side B is the souldful ballad-heavy second side, produced entirely by Linda Perry, which helps give this a sold, cohesive identity and and includes the track Hurt, another excellent pop record in the vein of Beautiful, also written by Perry.
