ROY ZIMMERMAN: 7:30 pm at Kenyon Hall:

The troubadour of the left brings us his take on current political and social issues, offering original songs performed with taste, style, and prodigious musicianship. His music speaks to the heart, and he juxtaposes outrage with hope, jolting us out of complacency into action. It’s powerful stuff, beautifully presented.
