Quick Song Question

Hi guys,

I was watching some of Day9's old day off VoD's on Twitch, and came across a song played during a break from the Antichamber video that I found really appealing, so I was just wondering if anyone maybe knew the artist or song title?

around 7 hours 11 minutes: http://www.twitch.tv/day9tv/b/410742710

Thanks :)
