The third annual Mill Valley Music Festival on May 11-12 combined elements of a delightfully eclectic daytime concert with a town fair, providing two days of entertainment for all ages in this quintessential Marin County locale. Headliners Greensky Bluegrass, Fleet Foxes, and many other performers thrilled adults and children alike, and a host of crafts and activities across the aptly named Friends Field provided hours of fun for those who preferred to keep the music in the background.
