Birds of a Feather was Killing Joke's first EP with new bass guitarist Paul Raven. It contained music that was artier and relatively calmer than the music from the band's first three studio albums, thus beginning a new direction. The new style was continued with the non-album singles "Me or You?" (1983) and "A New Day" (1984).
