From the Vault

From the Vault is the twelfth track heard on the Halo: Reach Original Soundtrack.

Appearances
This track appears in-game in Halo: Reach, but only within the bonus Tribute Room, playing alongside the Siege of Madrigal. Rather than being a purely original track, the piece is a medley of various musical themes from the Halo Soundtrack, Halo 2 Soundtrack, and Halo 3 Soundtrack, to the same tempo and percussion rhythm.

The pieces or themes featured, in order, are:
 * Farthest Outpost
 * Impend
 * The Maw
 * The Arbiter's Theme (Featured as the track 'Weight of Failure' in Prologue, and throughout the Halo 2 Soundtrack)
 * The track 'Overcome' from Behold a Pale Horse

Trivia

 * The namesake of the piece is a reference to the unique mixture of tracks that are taken from other soundtrack albums; thus, "from the vault." It may also be a reference to the fact it plays only within the Tribute Room, which is both a "vault" of past Halo/Bungie pieces and the well hidden and safeguarded lab of Dr. Halsey.
