Perhaps when prospective employers blather about "attention to detail," they're not-so-secretly pining for a candidate's potential to mimic a guy like painter Alex Stein. "Submughal" is Stein's painstaking enterprise consisting of six-inch mylar squares that in turn contain ten smaller paintings. The smaller paintings are fully realized and complete works of art in their own right. Stein discourages immediately studying his works with a lens, instead asking that viewers initially experience the lushness and jewel-like intensity before diving in to decipher intricacies on the micro level. This is Stein's third showing at Brooklyn's Safe-T-Gallery. "Submughal" opens tonight as part of the Dumbo Art Under the Bridge Festival, running all weekend-long, and ends in November.
