Tv midt-vest made an interview with Mattias back in 2011. It's a program called "Vis mig dit liv" ("Show me your life) and Mattias has some of his personal stuff with him and then tells a bit about them. A very good interview where you get to know much about him. He also talks a bit about Cille's exit and his feelings about it, something I hadn't really heard before. So check it out if you havn't already.
(In danish) - If you want, I can make a short translation to some of the video. Let me know if you are interested by leaving a comment.
