Our family (17 of us ranging from grandma (me) and grandpa to grandchildren in high school and college) will be staying in Tuscany for two weeks in June. Grandpa plays the harmonica and our grandson (age 20) is a very talented banjo player. Are there places in Tuscany or nearby where live music is played in a casual setting -- a setting in which our two family musicians can meet and perhaps jam a bit with other musicians?
