Photo: Carlos Avila Gonzalez / The Chronicle On a recent sunny Sunday afternoon, the sounds of live jazz wafted up and down Balboa Street in the Outer Richmond District as a small crowd sipped beer, munched on popcorn and moved with the rhythm. During the final set from Danny Brown and the Noise All-Stars in front of the closed entrance to the Balboa Theater, Emily Bridwell and her two young children arrived. As the musicians packed up their instruments, workers wheeled a big-screen TV out to the theater’s parklet, where Bridwell’s children plopped down to watch a free showing of “Toy Story 2.”
