A maximalist spectacle comprised of surrealist blown-glass figures, mind-boggling lenticular prints and ambitious installations reminiscent of bizarre movie sets, the De La Torre Brothers exhibition “Upward Mobility” came to light in March as part of the McNay’s 70th anniversary programming. On view through Sept. 15, the over-the-top show reveals characters and scenarios that artists Einar and Jamex De La Torre mined from both sides of the U.S.-Mexico border — from pre-Columbian deities and anthropomorphic cacti to a horrifically opulent dinner party.
