《24小时》是一出以24小时的播映长度分秒不差的叙述发生在24小时的事件为制播概念的影集。还剧自2001年秋季于美国福斯电视网首播以来佳评如潮。负责《24小时》音乐的是著名配乐大师西恩·卡拉利(Sean Callery)，这张电视原声收录了第一季到第三季的音乐创作。在《24小时》中，卡拉利以电子键盘为主干乐器，搭配运用丰富的弦乐编曲，以及特别设计的电子声效布局，来串接无止息的紧张情绪、悬疑气氛与惊悚效果，同时也不时借重弦乐的辽阔音域，来拉大动作场面的紧绷格局，或是升华主角人物的情绪撞击感触。 Fans of Fox television's real-time Kiefer Sutherland spy series 24 have been clamoring for a soundtrack since its first season. Released in conjunction with the arrival of the show's third season on DVD, and just a month before its fourth season debut, Sean Callery's moody, X-Files-inspired score works better on screen than it does on headphones. However, fans of the hit show will find much here to love, as the 19 tracks cover all three seasons, and the impressive liner notes provide everything from episode summaries to Callery's detailed account of scoring the pilot.
