Christina Aguilera Talks About Upcoming Disc

In an interview with Billboard, the singer said, "Some of the songs are kept authentic, sticking to a really raw, old-soul sound, where others combine elements of old blues, jazz and soul with a hard modern-day edge."

The singer is working with producer Linda Perry, a former member of Four Non Blondes.  Perry also worked with Aguilera on her last album, Stripped.
