Rutallica (commonly refered to as "The Circle Album", even though the album was only available in digital format) is the second EP by mashup band Rutallica. It contains eight tracks, made from a combination of songs by The Rutles and songs by Metallica. The reason why the cover is gray is unknown, possibly because The Triangular Album was meant to be white and not triangle.
"We've Arrived! (And To Prove It We Blackened)", "Sandman", "Leppo Messiah" and "Glamgri-La" were later re-recorded for the band's first studio album Sgt. Hetfield's Motor Darts Pub Band. "I Must Be Evil", "Now She's Trapped Under Ice" and "Choke Your Band" were re-recorded for Masterful History Tour.
