Twenty years ago, a group of Marin residents conceived of a plan to transform a piece of their community and connect with others through an art center. That idea is now known as Art Works Downtown, a multi-gallery space chock-full of talented artists and exciting exhibits. This weekend, the collective commemorates the last two decades with a new show, ‘20/20 Vision,’ that looks on the past, the present and to the future. The opening reception boasts live music from Danny Click, Jerry Hannan and Shana Morrison, art demonstrations and plenty of local food and wine. Saturday, Sept. 24, at Art Works Downtown, 1337 Fourth St., San Rafael. 6:30pm. $45–$55 and up. 415.451.8119.
