Destructoid reports the camp of Valve Software composers has just widen – Jason Hayes, a man of talent, left Blizzard. 

Now "electronic" Mike Morasky has a "symphonist" partner.

Up to the present, Jason worked for a long time with Blizzard, and then went to Carbine Studios, where he actively worked on unannounced MMORPG.

First job with Valve was sounding of Dota 2 Gamescom trailer, voiced by together with him and Tim Larkin.

Also, according to our knowledge Dota 2 was dubbed by his toughness John St. John (the voice of Duke Nukem).

Just yesterday Valve became generous and gifted us free downloading of Portal 2 soundtrack. This is the first part of music series, entitled as "Volume 1 - Songs to Test By" and contains 22 tracks from the original game. Further, as we understand it will be more interesting.

In addition, developers in a fit of generosity have cut and placed as a bonus a set of six recognizable tune fragments from the soundtrack for the iPhone and Android. And if you haven’t downloaded all that stuff, we advise you to do it as quickly as possible
