Ironically, Silvestri was not involved with the first Young Guns movie. That nod went to a jobroni composer named Anthony Marinelli who never created any other memorable scores. Alan Silvestri's Young Guns II score mixed a classic western theme similar to tunes heard in classic western films with a new age melodic hard rock guitar sound. The overture is heard throughout the movie, usually when Billy and his gang were riding onward towards their next escapade. The song kind of makes you feel like you are riding along as a member of Billy The Kid's gang. Just some powerful stuff, and very epic. Although not as recognizable as his other works such as the Back To The Future and Forrest Gump scores, I personally believe it's one of his best.
Ladies and gentlemen.... #22 Young Guns II Overture by Alan Silvestri
