It’s one of the most creative community-based events of the summer, a collection of art and music, food and local color, and it all goes down in the middle of the Petaluma River. This year, the fifth annual Rivertown Revival returns with multiple stages of music from local favorites like the Easy Leaves, Highway Poets and even performances from the Imaginists. There’s also a kids’ stage and plenty for the family, as well as dozens of homegrown vendors and a parade. The Rivertown Revival takes place on Saturday, July 19, at the David Yearsley River Heritage Center, 6 Copeland St., Petaluma. 11am. $5—$10. 707 290 6723.
