Dust and Echoes is the twenty-fifth track in Halo: Original Soundtrack.

Overview
The track opens with an eerie ambiance, quickly followed by reversed strings, which build up to a climax. The eerie ambiance continued, soon joined by the male choir, singing the main melody The Maw. The eerie ambiance briefly returns before strings take over, somberly playing a variation of the Halo Theme.

The reversed strings plays in the opening cutscene of the level The Library, when the activation index is shown in the Library. An extended version of the opening eerie ambiance plays in level Keyes, during the cutscene where John-117 retrieves the Flood-assimilated Captain's neural implants from the Proto-Gravemind. The track plays in full during the final cutscene of the level The Maw, when John-117 escapes the.

Arrangements
The track has been arranged into the following:
 * Wake Me When You Need Me in Halo 3: Original Soundtrack.

Production notes
The name is derived from Cortana's quote upon scanning the vicinity of the destroyed Installation 04, "Just... dust and echoes. We're all that's left."
