What music artists have you discovered through video games?

What music artists have you discovered through video games? That is, if you weren't playing a specific game you would have never heard and been introduced to music that you now like. I can point to Vice City regarding my infatuation with 80s pop; the whole genre. Introduced me to a whole new, awesome field. Games like Saints Row 2 continued that trend. Also, Remedy's games, specifically Max Payne 2, introduced me to Poets of the Fall. They're a band that I now listen to regularly; they're pretty good. Here's one of my favorite songs of theirs:
  

Do the video game ones count :(?

" Do the video game ones count :(? "

suburban all-stars please

module from shatter even though he hasnt done uch

Midnight Brown, I spose. :)

I can name some I discovered through movies. First off is Trivium on Smokin' Aces and the other one is Immortal Dominion on Teeth. Though there's only one I discovered on the God of War III soundtrack and that's Mutiny Within.

Anecdote time! 
Before I started getting into Rock Band, I didn't care much for music. Yes, the only music I was ever really exposed to was my sister blaring the Backstreet Boys or singing along to Kelly Clarkson, or my brothers' fascination with both the Star Wars and Matrix soundtracks. Rock Band, however, really got me into music, as pathetic as that may sound. While I had heard of most of the songs in the game, I'd say it introduced me to Radiohead, and decent Weezer songs, which I have kinda used as springboard inspiration for the majority of my current music collection.

Almost every musician the   playlist  of the GTA series

  Knew of these guys, but it wasn't until the MGS3 ending credits rolled in that I was instantly hooked, amazing ending to an amazing game.

 

2pac through GTA:SA:
 

Masashi Hamauzu and Jack Wall.  

Breaking Benjamin from a Michinima video 

" I'm surprised no one's brought up the Tony Hawk games. "

Kaiser Chiefs from Gran Turismo 4.

Way too many to list, especially if we're include Rock Band DLC @.@
 
My most notable would be Akiko Shikata, though. I adore her work.

The GTA series has formed my musical tastes more than I think I know.

For that matter Midnight Club too, Rockstar has soundtracks down.    

Everything from the first few Tony Hawk games :P

Does Guitar Hero count? I found out about a lot of artists through that game. Also, I discovered The Black Keys through NASCAR 09

" module from shatter even though he hasnt done uch "

I have a few: Obviously GTA:VC and GTA:SA, but also some of the music from K:Jah in GTA:3. 
 
Tony Hawk games, yes.  But again I knew most of those. 
 
Aggressive Inline, especially the Black Sheep, POD, and a few others.  That game actually had a better alternative soundtrack than the TH games of the time.  (That game also introduced the idea of getting challenges from people in the game world...) 
 
I obviously knew the Beatles before the Rock Band game, but it took me much, much deeper into their music. 
 
I think Still Alive by Lisa Miskovsky from the Mirror's Edge Soundtrack is an amazing song, although I haven't found another song by her that I like. 
 
I know OP said no Nobou Uematsu, but I would just offer that through the FFIV re-release on PSX that came with the game's sountrack, I got into his music from other games, including some that I either didn't play, or at least had just skipped right through.  I personally point to FFIX as my favorite, including the songs worked on by his two disciples.  
 
  

Bayonetta commercials got me listening to La Roux.

I found Anarchy Club in Guitar Hero II and really like some of their stuff.

Dirty three via Braid

Cage the Elephant who did the song 'Ain't No Rest For The Wicked' which is in the introduction scene in Borderlands.

Well, I really liked the song Right Now by SR-71 found in the game Splashdown and How Crazy Are You? by Meja from the Dead or Alive Xtreme Volleyball games, but the only artist I've listened to outside of what's featured in video games is Hikaru Utada.  She did the title in Kingdom Hearts ( Simple & Clean) and the sequel ( Passion), as well as some anime (Evangelion ~ Beautiful World).  I bought her albums Exodus, Colors and the Singles Collection Vol. 1.   She's very talented in my opinion and quite lovely as well. 

That guy Baiyon from the Pixel Junk games and other stuff.

Tales of the Abyss introduced me to Bump of Chicken. Mass Effect got me addicted to Faunts. I didn't know about Cage the Elephant before playing Borderlands. I also discovered Poets of the Fall via Max Payne 2 and they've been one of my favorite bands ever since.

" I'm surprised no one's brought up the Tony Hawk games. "

Hollywood Undead

I've heard odd tracks that I've liked here and there in games, but for me the biggest influence that video games have had on my musical listening habits comes from Grand Theft Auto IV. While their take on classic rock radio was pretty hit-and-miss before more tracks were added with The Lost & Damned DLC, one song in particular grabbed me - Remedy, by The Black Crowes: 
  

Really, the grand theft auto soundtracks have introduced me to tons of artists, and I have thousands of songs that I attribute to getting because of GTA.  
 
Tony Hawk got me into Hip-Hop as well, and now I have a ton of hip-hop songs.

Jun Senoue, mainly because of "Escape From the City". 
MISIA, Ending for Star Ocean 3 and that "wait for Sophia" entrance(The Little Bird)

Akira Yamaoka mostly.

Klaxons and Bloc Party from Need for Speed Prostreet, now both are some of my favorite bands.

Tony Hawk: Underground for the PSP introduced me to Atmosphere
 
the song "Trying to Find a Balance" was so awesome I had to find out who sang it.
 
I'm now a gigantic Atmosphere fan, even though their work is a bit hit and miss, when it hits, oh man. Just some amazing hip hop.

The last one I can remember is Audio Bully's from that APB trailer, if that counts

Way back in the good Tony Hawk days, I found tons of bands like Goldfinger. Those games have excellent soundtracks.
