Monkey Island 2: LeChuck's Revenge

Michael Z. Land worked on sondtrack for Monkey Island 2: LeChuck's Revenge (1991) with Clint Bajakian, Robin Goldstein, Peter McConnell and Anthony White. This is also the first game to use the Land's developed iMUSE for LucasArts.
One often cited example of the iMUSE system is at the very beginning of Monkey Island 2 where Guybrush finds himself in Woodtick, the small town on Scabb Island. Whenever Guybrush walks into a building, a variation of the Woodtick theme plays, each with a different instrument. When Guybrush then walks out again the music has a closing flourish that leads back in to the basic Woodtick theme.
