Anthem is the fifth studio album by American ska punk band Less Than Jake, released on May 20, 2003 on Sire Records. Produced by Rob Cavallo, the album was preceded by the single "She's Gonna Break Soon", and was the band's most commercially successful album to date, reaching number 45 on the Billboard 200. During the recording sessions, the band worked on a second, self-produced album of additional tracks each night after Cavallo left the studio. This was subsequently released the following year under the name B Is for B-sides.
