‘Bye Bye Babylon,’ the title of Erik Parker’s latest solo show at Paul Kasmin Gallery, and his subject matter – edenic landscapes teeming with psychedelic flora – suggest he’s left the city for greener pastures. In fact, he’s still Brooklyn-based but uses the exotic locales he depicts to take a mental break from urban life. (Through October 13th).
