Album of the Day - Danger Mouse "The Grey Album"

This collision of Jay-Z's "Black Album" with the Beatles' "White Album" is a beautiful sonic adventure. I will admit upfront that I have not heard either of the source albums, but I hope someday to rectify that. That said, this record is a fantastic combination of the two. At no point does anything sound forced or unrelated. The music fits the vocals and hip hop beats quite well. Wikipedia has the tracklist, including which Beatles samples were used for which songs.
