Gibbs opted not to devote full time to the regular series' production, due to scheduling conflicts: he wished to devote more time to scoring theatrical films. As a result, Bear McCreary scored "33" (which was actually the first episode) and then stayed on as soundtrack composer for all subsequent episodes of the series. McCreary is credited as sole composer for 26 of the 30 tracks on the Season 1 soundtrack. The total running time of the album is 1:18:19. Irish singer Lilis Ó Laoire sings in the Irish language on "Wander My Friends".
