F4LL0UT: Wow, blast from the past much. I had no idea Klepacki was involved again and I certainly didn't expect his current music to sound so much like his good old C&C tunes (I still regularly listen to the original game's OST btw). I'm curious what the other music in Grey Goo sounds like. I hope the music is going to be as diverse as in the earliest two C&C games, although I doubt that's gonna be the case.
The way I understand it, used soundtrack heavily depends on the race you're playing, with different races having wildly different thematization. From the presentation I've seen in TB's WTF is... video, there's even an in-game music player, where you can choose and mix which music you wish to have played.
Is all of it going to be as old-school tho? No idea. It sounds like human songs are, betas are more orchestra-oriented, and the goo is going for more of a dubstep approach. All of it sounds like quality music tho - after all, it is still Frank Klepacki.
Then again, the linked song is Beta's track. Damnit, I have to play the game just to find this shit out.
