Today's show has a bit of an edge, or perhaps it is walking towards one.

Renowned guitarist G.E. Smith will be playing a solo show and teaching a masterclass on the history of guitar both benefiting Belchertown Music Boosters, a local organization dedicated to supporting local arts programs in the Belchertown school system. After a bit of miscommunication, we're able to chat with the award winning sideman about the folx he's worked with, his start on guitar, and why helping programs like this is important.

We speak with him about the book, and about his evolution to philanthropist after giving away the fortune he'd inherited from Oscar Mayer.
