The glass armonica is an instrument that *Benjamin Franklin* invented in seventeen sixty-one. Playing it is Dennis James - one of the few masters of the instrument. Franklin was inspired when he saw a player of the "musical glasses."
Dennis James is playing the Lake Music Festival Friday, July 19th. Ticket info is at Rochesterfirst.com.
