I am listening to Outkast's new outstanding album Speakerboxxx/The Love Below. Both in packaging and in content it is really rather a 2-disc album collection rather than a double album. I'm not really up to date on the inner workings of Outkast, but it appears the Outkasters just produced one album each in their own style, instead of trying to make two rather different styles meet. The end result is one contemporary sounding (more electronic) hip-hop album with solid funk roots, and another album which is more easily described simply as modern funk.
