Juno Reactor and Midnight Syndicate rule (and Ed Douglas is a great guy). I could be biased there, of course, since I wrote the flavor text on their last album, but I loved them long, long before that.
The Rock score is awesome, but my favorite score of all time is probably
Crimson Tide, which I play a lot when writing. My needs at the keyboard are often similar to those of gaming - few vocals, inspirational instrumentation, etc. - but it all depends on what I'm trying to accomplish. In terms of mood, I'm very much a method writer, at least emotionally. The sky's the limit, though, when I'm writing rules, editing, laying a product out, or handling general administrative stuff. Then I listen to the full range - everything from VNV Nation to Groove Coverage to Jack Off Jill to Poe.
Speaking strictly of gaming noise, though...
Hideaway soundtrack (the last four tracks are gold for horror games, and as an added bonus, the disc features some bad-ass tracks from KMFDM, Sister Machine Gun, Miranda Sex Garden, and others)
The Fog score (one of the best cinema discs ever)
Escape From New York score (ditto - also from John Carpenter)
Halloween score (I'll stop with the John Carpenter stuff now - his early score work is all fantastic)
Planet Terror score (okay, one more - this one is pretty seriously germinated by Carpenter's work - it even incorporates some of the original rifs)
Doctor Who scores (from the new show - they're quite good)
13th Warrior score
Speed score
Deep Impact score
Professional/Leon score
La Femme Nikita score
Arrival score
Mimic score
Usual Suspects score (fantastic for 10kB)
Blade Runner score
Dragonheart score
Rocketeer score
Pan's Labyrinth score (easily one of the best of 2006)
Alien movie scores (especially
Alien 3)
Terminator movie scores (especially the first two)
Any of the Cirque du Soleil stuff (no, I'm serious - it's awesome for ambient enterprises)
And for my money, the best Bond score by far was
World is Not Enough (which also featured one of the best title themes of the entire 21-movie run)
Good gaming composers: Mark Snow (
X-Files,
Disturbing Behavior,
Smallville,
Syphon Filter, and about a million other things), Christopher Franke (
Buffy,
Babylon 5,
Thief score - which is stellar,
Legend,
Firestarter, and again, about a million other things), E.S. Posthumus (parts of
Spy Game,
Planet of the Apes,
Time Machine, and other stuff), Carl Orff (
Carmina Burana,
Antigone), Jerry Goldsmith (
Man From U.N.C.L.E.,
First Blood and
Rambo: First Blood Part II,
The Mummy,
Alien Nation,
Poltergeist,
Logan's Run,
Patton,
L.A. Confidential,
Psycho II, and more than I can possibly list here - he is deeply missed), and the aforementioned Hans Zimmer (
Crimson Tide,
Gladiator,
Last Samurai,
Pearl Harbor,
Pirates of the Caribbean), Howard Shore (
Lord of the Rings,
The Game,
Se7en,
Silence of the Lambs), Graeme Revell (
The Crow,
Sin City,
From Dusk til Dawn), James Horner (
Willow,
Cocoon,
Legends of the Fall). Everyone loves John Williams, and he's really good, but his stuff is
so iconic that I find it largely useless for gaming purposes.
Good gaming bands: Cruciform Injection (the guys who made the
Obsidian RPG - they often play at GenCon Indy), Dead Can Dance (also good for horror), Tangerine Dream, Vangelis, Crystal Method, Orb, Paul Oakenfold, Cruxshadows, Covenant, Conjure One, And One, Clan of Xymox, Bella Morte, Birthday Massacre, Apoptygma Berserk, M83 (their "Unrecorded" was used in the original
Nightwatch trailer). Some of those bands produce lots of stuff with words, so it's a mixed bag if your group is prone to distracts from background noise. All of them produce at least some non-vocal stuff, though, and all is evocative and atmospheric.
If you can find them, I also recommend the Blizzard scores (World of Warcraft, Starcraft, etc.). Good stuff.
And of course, for fantasy, nothing touches Basil Poledouris'
Conan the Barbarian score.
