Beatallica (known by fans as The Grey Album) is the second E.P.

It contains eight tracks, made from combinations of Beatles and Metallica songs.

The gray color of the album cover is a reference to both The Beatles and Metallica's self-titled albums (the former being white and the latter being black, gray being the resulting combination of both colors).

"Blackened the USSR", "Sandman", "Leper Madonna" and "Hey Dude" were re-recorded for the band's first full-length album Sgt.

"And I'm Evil", "Got to Get You Trapped Under Ice" and "I Want to Choke Your Band" were re-recorded for their second album Masterful Mystery Tour.
