Destructoid has stated that composer Jason Hayes has moved to Valve. You might know him as the award-winning musician behind StarCraft, Diablo II, Warcraft 3 and World of Warcraft. He joined Carbine Studios a while ago, but now, he’s joined Valve, and is currently working on Dota 2.
You might think you’ve never heard his work, but think again! The official Dota 2 trailer’s soundtrack was composed by him, along with Tim Larkin, one of Valve’s sound designers.
I wouldn’t be surprised if that was his work we heard in the CS:GO trailer too – it had his signature “epic, orchestral style” to it, as Destructoid put it. Of course, I still believe that Zak Belica and Chris Jensen are the only two people I would trust with making a Counter-Strike soundtrack. Still, I’m very excited to hear about this, and I hope Jason helps make Valve’s music even better than it already is.
