The dominant aesthetic of “Freak Out,” exemplified by the work of Tim Eastman and George Rippon, is as fussy, meticulous and inventive with materials as possible while still credibly maintaining a shrugged-off feel. Seemingly banal imagery carries a conceptual hook, as in Genoveva Filipovic’s watercolor of a parrot, Drawing for a Steak House (2012). Digital tools are treated not as exotic new media but as regular stuff in the work of Trisha Baga and Ian Cheng. With 34 artists, both emerging and emerged, “Freak Out” is like a casual biennial, the art world’s version of a 2013 summer jam.
