If the Shepard Fairey name holds no allure, surely Subliminal Projects’ vibrant, celebratory group shows will. For most of its life, the street artist-owned gallery has curated and hosted mixed-media shows with a lineup of local artists whose work is rooted in activism and community healing. On the other end of the spectrum of exhibitions, Fairey has used his connections to showcase notable blips in alternative culture, such as a show of Dee Dee Ramone’s artwork or a celebration of Black Sabbath with portraits, fan photos and other ephemera provided by the heavy metal band’s family and estate. Subliminal Projects is as flashy as it is scrappy. Bring your out-of-town friend who wants to do something equally touristy and cool.
