Shreddin'

Shreddin', also titled Old Stuff, is a music piece that appeared in Halo: Combat Evolved, but was not featured in Halo: Original Soundtrack. However, it was later released as a free download on Bungie.net in 2002.

Appearance
The music appears in-game as flip music in the campaign level 343 Guilty Spark, when the John-117 is playing the recording chip from Wallace Jenkins' helmet. It plays when Avery Johnson and his squad are aboard the Pelican enroute to the Flood containment facility. A second section, featuring an electric guitar solo, was omitted from its in-game appearance.

Production notes

 * Matt Soell noted that track draws inspiration from the works of Ozzy Osbourne and the opening is similar to "No Sleep Till Brooklyn" by Beastie Boys.
 * Judging from datamined info from Halo: Combat Evolved Anniversary, Shreddin' may have originally been intended to be Rock Anthem for Saving the World before it was replaced with the final piece. It features interactive elements like other tracks in-game, such as an introduction, alternative loops, and an ending.
