Being in the Philly area i love this post for a couple reasons, first off Dr Dog is a local Philly band, sadly they are calling it quits but they are doing 5(?) shows are a couple venues as their farewell tour around the new year. Second, WXPN radio, listener supported radio, like you said, they don't have a play list they need to follow, they play what they want and like you, i have discovered so much amazing music through them.
