"In 1982, France’s Ministry of Culture dreamed up an idea for a new kind of musical holiday. They imagined a day where free, live music would be everywhere: street corners and parks, rooftops and gardens, store fronts and mountaintops.
And, unlike a typical music festival, anyone and everyone would be invited to join and play music, or host performances."
