Read Dead Redemption is one of my favorite PS3 games, not only for the game play but for the beautiful environments, musical soundtrack and flawless sound design.
I am posting a link to an in depth interview the audio director of Red Dead Redemption.

The interview is by Miguel Isaza for designingsound.org

When I saw the first images of Red Dead Redemption I knew that it will be a beautiful and amazing game. Then, the gameplay confirmed me that not only the visuals were great. The sound work there was fantastic. Clean mix, great sounds, and a perfect sonic experience for any player. So, if like me, you wanted to know more about the sound direction of the game, here is an interview with its audio director Jeffrey Whitcher.
