Based on the Fox television drama series 24, The 24 Soundtrack contains nineteen tracks of music composed exclusively for the first three seasons by producer Sean Callery, including the show's full theme song which has never been aired. The music contained in the soundtrack is somewhat of a hybrid mix of electronic pulses and rich orchestral textures that is meant to give each episode its own sound, yet at the same time have a sound that is consistent with the rest of the series in a way that compliments the show's "real-time" format.
