October is the perfect month for gallery visits, when the season is back in full swing and great weather makes it irresistible to get out and see what’s new. Among the best shows is Doug Aitken’s latest solo at both locations of 303 Gallery, where the mesmerizing video ‘Migration,’ stars American migratory animals confined in rooms at a series of down-at-the-heel motels. A bison knocking down chairs, a deer sipping from the pool and beaver in the bathtub suggest that animals can survive our encroachment – but can we? Speaking of animal nature, Cecily Brown is back with more paintings exploring her signature subject matter – sex. The act is discernable in a few canvases but most are abstract, allowing viewers to make their own conclusions about where her writhing brushstrokes take us. Ernesto Neto’s social spaces are decidedly more public. For his sixth solo show at Tanya Bonakdar Gallery, a cave resembling a giant caterpillar takes up residence on the ground floor while upstairs, architectural maquettes allow visitors even more intimacy with the artist’s ideas for the space around us.
