Cairo Suite

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 and The Armory.

The song starts with military-style snare drums, and quickly turns into The Last Spartan, a track from the first Halo 2 disc. Around 2:00, 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.
