Those need to get released, somehow someway. Hearing GPN live is the way to listen to them, the energy, the groove, the vibe whatever you want to call it is there. Since I downloaded the 2-26 Atlanta show (that I attended) that is just about all l listen to. While it is a very good recording I can only imagine what a 8track recording would sound like. 
Here is to hoping that we get to hear these sooner rather than later.
