The Soundtrack for Half-Life 2: Episode One contains several pieces of original music used throughout the game and composed by Kelly Bailey.

The Soundtrack was also included in the game directory of both demo and full Audiosurf releases on Steam, and in the bonus CD of the Russian version of The Orange Box.

In September 2014, to celebrate the release of Steam's Music Player, Valve re-released the Soundtrack for Episode One as free DLC available to those who own the game.[1]
