Looking back at the liner notes, he was credited five times on that project. 3 production credits and mixing credits on Up North Trip and Trife Life. That Red Bull Academy interview made it seem like he did a little more though. The 53min 25sec mark is where they discuss The Infamous http://vimeo.com/redbullmusicacademy. You can tell he cleaned that album up a lot.
