The men behind Portal's musical score

Portal’s ending theme may well be one of the greatest video game songs ever created, and the duo behind it are also working on the sequel’s music. Jonathan Coulton:

I live and die by the niche, basically. I write all these geeky songs. It’s Internet people who keep me afloat for the most part. But then, suddenly there was this Portal thing, and it was a global phenomenon, and it reached all sorts of people that I wouldn’t have otherwise reached.
