Of Mice & Men is a metalcore/alternative metal band formed in Costa Mesa, California in 2009 by Austin Carlile and Jaxin Hall after Carlile’s departure from Attack Attack! The name of the band is derived from John Steinbeck’s novel of the same title.

The current line-up consists of Phil Manansala (guitar), Valentino Arteaga (ex. Lower Definition; drums), Aaron Pauley (ex. Jamie’s Elsewhere; vocals/bass guitar) and Alan Ashby (guitar).

Shortly after forming, Carlile and Hall enlisted the help of Though She Wrote to create their first collaborative demo track “Seven Thousand Miles for What?” and later began recruiting the remaining band members.
