For "Myst III: Exile" and "Myst IV: Revelation", composer Jack Wall created the music, developing a more active musical style different from Miller's ambient themes. Wall looked at the increasing complexity of games as an opportunity to give players a soundtrack with as much force as a movie score, and tried to create a distinctive sound that was still recognizable as "Myst" music. In "Revelation", Wall adapted the themes for the recurring characters of "Myst", and collaborated with Peter Gabriel, who provided a song to the game as well as voicework.
