Young film scorer Michael Giacchino built his reputation sending up a few decades worth of spy score cliches via his rich, eclectic cues for TV's Alias, shedding his TV/video game journeyman's mantle with the full-bodied, swinging jazz score for Pixar's The Incredibles. His work for producer/creator J.J. Abrams' (who also penned the series' brief theme included here), Lost, allows Giacchino to better showcase the range of his mood-setting musical talents, echoing the show's more cinematic, genre-blending conceits. To that end the composer relies on musical cues that range from the moody, percussive drone of "The World's Worst Beach Party" to the tense, McAction film stem-winding of "Monsters Are Such Interesting People." As always, Giacchino's playful cue titles suggest just how much fun he's having tweaking even the hoariest of film music conventions.
