CM Punk is a huge music fan, his world view and lifestyle is built around the punk rock world. Given his enjoyment of the music industry and the wealth at his disposal, you can't rule out him getting involved in the punk rock scene in either a promotional or producer capacity. Punk is a smart guy, he was promoting and managing his own wrestling federation at a young age, if he loves something he is typically motivated to get invested in his passion. Having done wrestling, his punk rock passion could be his next project. Given his close friendship with Rancid guitarist and vocalist Lars Fredriksen, Phil Brooks certainly has the connections. A formal partnership would put together the creative and commercial forces needed to perhaps find success in the music industry business scene.
