"Music by Sean Callery" is a special feature found on the Season Five DVD. It was directed by Eric Neal Young. The feature begins with Sean Callery, the composer for 24, explaining the sort of music he uses on the show. He demonstrates his working area; a room with several keyboards, a mixer for working on sound design, and several television monitors showing what he is adding the sound to. He also shows what he calls his "isolation booth", with an old style, real piano that also records everything he does so that he remembers all his work.
