Here's the link
Apparently Microsoft studio is hosting an official Halo 4 remix contest, complete with stems from the upcoming soundtrack within the game... I thought that those who weren't aware of this (it was posted in a little link as I was checking my soundcloud today), it would be a good chance for some of NG's artist to give it a go and maybe give a little rep to our site...
I might enter, but I haven't examine the stems yet... but hey, might as well try right?
Btw, if you have any specific questions about this, I'll just let you know right now that I'm just as clueless about the whole thing as the next person, so I might be more aware of what's going on with the contest as I further examine it, but right now, I just found it and was posting it here so many artist here could see as well.
