On Thursday musicians strapped on their guitars and warmed up their vocals for the "Make Music Black Hills" festival.
It all started 35 years ago in France when Jack Lang and his staff at the Ministry of Culture dreamed of a new kind of musical holiday.
Now France shuts down on the summer solstice and musicians take over the streets in the spirit of free music anywhere.
And on Thursday 11 locations in the Black Hills joined 120 other countries in this worldwide celebration.
Bruce Douglas performed at the Suzie Cappa Art Center for the festival.
Bruce Douglas says, "The person who's playing the music, makes them feel good and it makes people who listen feel good, too and I feel like I can connect with people. I'm generally kind of a shy person and music allows me to come out." >
