Siege of Madrigal

Summary
In the Halo 1 level Assault on the Control Room, there are a couple places where you can stand and hear a song from Myth, another Bungie game, called the Siege of Madrigal. One can be found on the pyramid structure at the end of the level. There are three brackets on the large tower, get a Banshee and land on the second one. Facing the cliff, go to the right side of the bracket and wait a few seconds. If you can't hear it, walk around a bit to find the right place.
