John of The Zeray Gazette has a neat compilation of various video clips of Enter Sandman, the iconic song by Metallica, as covered by others and played in um, different genres.

Included are: Enter Sandman as performed by the bluegrass band Iron Horse, the cello quintet Apocalyptica (quite famous, actually), and even a version played with a Kazoo!
