Battle of Mice was an American post-metal supergroup consisting of Julie Christmas, Josh Graham, Joel Hamilton, Tony Maimone, and Joe Tomino.
Graham and Christmas were in an on-again-off-again relationship during the recording of the band's debut album, A Day of Nights.
Released under Neurot Recordings, the album contains seven tracks heavily influenced by the metal, post-rock and noise rock roots from which the group was derived.
In March 2008, Josh Graham revealed an interview that Battle of Mice was currently "on an indefinite hiatus".
He also said that the band recorded two songs, about nine months after A Day of Nights was finished, for a split EP with Jesu on the Robotic Empire label.
