A new version of the iMUSE interactive music system incorporating MP3 compression, among other changes, was built and used for the game. Interactive programming of the music and ambiance streams in the iMUSE system was done by lead sound designer Larry the O. "Escape's" introductory music is identical to that of the third game, unlike the earlier sequels which featured newly composed remixes of the well-known "Monkey Island" theme. Clint Bajakian, who had previously been an additional composer on "Monkey Island 2: LeChuck's Revenge", acted as the game's main composer, with additional tracks by Michael Land (who had been the lead composer on the previous three "Monkey Island" games), Peter McConnell, Anna Karney, and Michael Lande (not to be confused with Michael Land).
