Just for completeness's sake, someone on the inforoo facebook brought up that Moon Taxi's latest album had Buck Mountain on the cover. They have played before, so the lunch box could just signify them as a returning artist. Not sure how the radio clue would apply to them though.
I would like a formal apology from David Maynar for this post. Which was right after my brilliant, insightful AND correct historical essay on lunchboxs and how it made the answer Sturgill Simpson.
