San Francisco’s SoMa neighborhood, like much of the city, is a picture of disparate details: luxury, innovation and fine dining, shadowed by rampant homelessness, substance misuse and human suffering. It seems appropriate, then, that SoMa’s 111 Minna Gallery is no home to vacuous art. In recent months, gallery owner Michelle Delaney has deftly selected artists who reflect the murmur of darkness and absurdity beyond the gallery walls. The latest selections are no exception. On July 14, 111 Minna celebrated the opening of solo shows by Bay Area artists David Ball and Guy Colwell.
