As we attempt to apprise our readers on even a fraction of the endless arty sweetness that is CAM, we’d be remiss not to mention Saturday’s opening of “That Thing on the Side of the Road,” a show that thematically pairs music and visual art in a unique way. Curated by UTSA professor/all-around badass Hills Snyder and presented by the Spare Parts Mini Art Museum, the show unites 17 visual artists and eight musicians — all responding, in their own mediums, to the titular phrase. The resulting small-scale artworks and songs promise to be as diverse as the impressive group of artists Snyder recruited.
