Cairo Suite is a suite of songs included in the Halo 2: Original Soundtrack. It includes Cold Blue Light, Waking Spartan, Jeweled Hull, and Chill Exposure. Parts of it are played during the levels Cairo Station and The Armory.
The song opens by echoing the Opening Suite from the Halo: Original Soundtrack until around 1:50, when the suite switches military-style snare drums, and quickly turns into The Last Spartan, a track from the first Halo 2 disc. At around 5:30, the tracks takes on a mystic, reverent tune, with echoing digital noises sounding in every few seconds. This lasts for a minute or so before changing to digital chimes, and from there onto more digital noises and fragments of soft choirs. This goes on until the song concludes with a gong.
