Favourite video-game OST composers

I loved the stuff by Jonathan Coulton in The Orange Box

Particularly Still Alive

well there is Jeff van Dyck who has done lots of the music/sounds from the Total War games. You get a nice cd of music if you buy the Eras box set.

More recently there is Amon Tobin who did the music for a Splinter Cell game. Whilst I'm on the topic check out Jesper Kyd as well (did some work for Hitman).

And how can you not love the Super Smash Bros. sound tracks? I've got a (freebie-cd) take on things from The Tokyo Philharmonic Orchestra which is very nice.

Probably Kow Otani's SotC soundtrack, as it's basically twenty epic over-the-top mindblowing boss battle themes.
I've also been surprised by Hitoshi Sakimoto's Vagrant Story OST, Harry Gregson-Williams of Narnia-fame with his Metal Gear Solid OST and... I'll edit if I think of something else.

Jesper Kyd...gotta love the Hitman OSTs

As my top albums chart shows, I've listened a lot to Shunsuke Kida's Demon's Souls soundtrack. Unlike many video game OSTs, most tracks can be listened out of the game and still sound great and complete.
I loved Kow Otani's work on Shadow of the Colossus, which was very well integrated in the game. Unfortunately, out of context it seemed dull and unpolished.

First of all, I'd like to add to the love for Jesper Kyd - fantastic composer. The Hitman series' soundtracks are my favourites of his (particularly Blood Money).

Then there's Adam Skorupa. He, along with Paweł Błaszczak composed the The Witcher soundtrack. A slightly dark fantasy soundtrack.

Jack Wall and Sam Hulick did a great job on the Mass Effect and Mass Effect 2 soundtracks. Jade Empire is also a good OST if you're into Eastern-themed music.

Jeff van Dyck's soundtracks added lots of immersion into the Total War games, I recommend you check out the soundtracks. The Total War: Eras box set is a good place to start.

Then there's also Jeremy Soule, known for soundtracks to the Elder Scrolls series. My favourite is TES IV.

One of my other favourites is Peter McConnell, who composed the soundtracks for Grim Fandango and Psychonauts. I prefer the Psychonauts soundtrack, but that's probably because it's my favourite game of all-time.

The Halo series soundtracks are pretty good too. They are like epic fantasy soundtracks with an added sci-fi touch.

We also have Shawn Lee (Bully), Stephen Rippy (Age of Empires III), Inon Zur (Fallout 3 and Dragon Age: Origins)., Jason Hayes (World of Warcraft), Kai Rosenkranz (Gothic 3) and Kyle Gabler (World of Goo).

Chris Vrenna did a fantastic job on American McGee's Alice, it's clearly influenced by his earlier industrial works, as the soundtrack is creepy and uses a lot of samples of angelic voices and breathing.

From VA releases, I'd recommend the Fallout 3 soundtrack (full of 30s-50s pop songs), the LBP soundtrack (very "fun" music, love My Patch and Tapa Niang the most), Total Overdose (latin-like), Midnight Club II ("clubby" music) and the Scarface: The World is Yours soundtrack (over 100 tracks - all popular songs from the 70s and 80s). The Battlefield Vietnam OST is great too, added a lot to the atmosphere.
