when i saw that it said "From February to July" i had though that the spring deadline was sunk, then i realized your link was posted February last year.
Back then, BRINK was set to launch in Sept. 2010.
EDIT: On http://www.bobandbarn.com/downloads/index.php?page=ambient you can listen to some sound-samples btw.
EDIT: I recommend you listen to the following samples:
http://www.bobandbarn.com/downloads/force-download.php?file=ambient_human_experiments.mp3 Human Experimentation (ambient)
- I can imagine something like this for a cutscene in the sewer-area (Aquarium).
http://www.bobandbarn.com/downloads/force-download.php?file=kfc_dojo.mp3 Kung Fu Chaos: Dojo (funk)
- WIth a little less asian, but more western orchestral elements, something similar could be the campaign-opener for either faction, showing you the ARK from a great birdview.
http://www.bobandbarn.com/downloads/force-download.php?file=fusion_hillfort.mp3 Hillfort Fusion (fusion)
- this just generally fits the description of what they're working on for BRINK, imo. Also something like it could come with the finale of either faction's campaign.
http://www.bobandbarn.com/downloads/force-download.php?file=orch_primal_arella_weakening.mp3 Primal: Arella Weakening (orchestral)
- again a campaign-opening stylised theme.
http://www.bobandbarn.com/downloads/force-download.php?file=Misc%20-%20VFF.mp3 Virtual Freedom Fighters (other)
- this is not really anything specific, but I think the style would fit BRINK the most.
