Today is the annual Music Festival that happens all around the world on this date each year. It was started in France in 1982 but has grown into an international festival. So, all throughout town I couldn't walk 50 feet without tripping over a band or musical act of one sort or another - it's a lot of fun and its totally free.
This band, called Alexis and the Brainbow, was one of my favorites. They are French but sing in English, you can listen to them HERE.
