What is the score that plays during the Cochinay assault in the mission "And the Truth Will Set You Free" in Red Dead Redemption?
Solution 1:
First off, you might want to edit the question to remove the spoiler. (re Dutchman Final mission)
The Official Red Dead Redemption soundtrack is available via iTunes
or as a physical CD from Rockstar directly.
I'm thinking that the music that you are looking for is actually from the Score not on the OST though. I don't think that music is officially available.
