The Metal Gear Solid series has consistently delivered some of the best original soundtrack material in games, due in large part to the orchestrations of Harry Gregson-Willams. Those smart enough to have picked up the Limited Edition Bundle of MGS4 were treated to a bonus CD featuring 16 tracks from Gregson-Williams' killer score for the game.
For those not in the know, Harry Gregson-Williams is one of the most prolific composers of the past decade or so, with film credits ranging from "The Rock" to the upcoming "Wolverine" movie. Gregson-Williams is also unique since he is a film composer, who was sought out to lend his style to video games, starting with Metal Gear Solid 2: Sons of Liberty and continuing through this latest game. In fact, the only other game soundtrack to feature his music so far is Call of Duty 4: Modern Warfare.
