LP, in both the climates of the current economy and the imploding revenue from the music industry you release a physical CD for a relatively tiny audience, with an uncertain amount of consumption due to the entire package's cost, and yet you don't include 2 demos that you may or may not even still have copies of? you release higher quality versions of existing demos, uncover some new songs for the fans and go out of your way to grant them special access to shows, Meet & Greets and International Summits instead of these two songs? LP, your priorities are shit. Sort it out guys..
