Roots, Shoots and Leaves' DJ Tree has a theory of music that involves a tree. Suffice it to say that it involves a trinity — an exploration of themes and connections among recording artists — and otherwise very few boundaries. Listen for music old and new, known and unknown. And if you listen long enough, you may experience some musical enlightenment.
Occasional subbing in this timeslot is Bill Wagman with Evening Becomes Eclectic: "Folk is connected in so many ways to blues, rock, jazz, punk, and other forms and is universal worldwide." Bill works to explore those connections.
