I've noticed a lot of interesting opinions regarding composers in a few threads recently, so I figured this could bring up some interesting conversation.
List your favorite composers (film, tv, games, etc) and what works you like them best for. Feel free to add in some additional insight on why you like their work.
Harry-Gregson Williams (Metal Gear Solid 3: Snake Eater, Call of Duty 4)
-His MGS3 soundtrack really captured the mood of 1960's espionage, and really served as a great opposite to the previous, electronic-infused Metal Gear Solid 2 soundtrack. Call of Duty 4's soundtrack provided great orchestrated action cues that weren't off the walls insane like the newer games in the series. The pieces he composed for the All Ghillied Up mission still send chills down my spine and occasionally draw tears. Definitely the best soundtrack of all the Call of Duty games.
Ian Livingstone (Company of Heroes, Company of Heroes: Opposing Fronts, Company of Heroes: Tales of Valor)
-While everyone recognizes Jeremy Soule for the Company of Heroes soundtrack, I personally find Ian Livingstone's tracks to be the height of the soundtrack. Since all his tracks are for the British faction, I usually find myself playing as Britain because of how great the music is.
Daft Punk (Tron: Legacy)
-I like these guys solely as film composers. I've listened to some of their music, and I know I'm going to be bludgeoned for this, but I don't really care much for their actual music. Derezzed, Castor, and End of Line aren't really my favorite tracks on the soundtrack, consequently. But I feel like the electronic Hans Zimmer style really worked out in the end. I won't post a video for these guys since all of you have likely heard every track from the soundtrack about a million times.
Michael Giacchino (Medal of Honor: Frontline, Medal of Honor: Airborne, The Incredibles)
-This guy has composed the music for all the Medal of Honor games (sans Rising Sun, Pacific Assault, European Assault, and the 2010 one), and while I love the music from all of them, I find Frontline and Airborne to be the height of the series' soundtracks. Frontline's use of slow, emotional songs was incredibly unique for a World War II shooter, and Airborne's use of music from previous games along with the new music composed for the game ended up making the game feel like a respectable wave goodbye to World War II for the series. Regarding The Incredibles, I think it can be generally accepted that it had a really great soundtrack, so no need to explain there.
