When was Metal Gear Solid 4: Guns of the Patriots released?
Metal Gear
Soundtracks for the first two games were produced by Iku Mizutani, Shigehiro Takenouchi, and Motoaki Furukawa. For Metal Gear Solid, Kojima wanted "a full orchestra right next to the player"; a system which made modifications such as tempo and texture to the currently playing track, instead of switching to another pre-recorded track. Although these features could not be achieved at that time, they were implemented in Metal Gear Solid 2: Sons of Liberty.[136] Hideo Kojima chose Harry Gregson-Williams, a Hollywood film composer from Hans Zimmer's studio, as the composer for Metal Gear Solid 2 was highly publicized in the run-up to the game's release.[137] Gregson-Williams would reprise his role in Metal Gear Solid 3 and Metal Gear Solid 4.[138] Starting with Metal Gear Solid, theme songs have been provided by popular artists such as Rika Muranaka.[139] Several soundtracks based on the games have also been published.
