“I think golems are very transgender — they’re beings that are often perceived as monstrous, who have tremendous power and are made by humans through magical means. Not to mention, they’re sexy as hell,” says Aviva Pearl, writer of “Clay Mommy,” a play that explores trans identity and its own unique form of motherhood. Pearl, who wrote it, teamed up with her friend Jael Scott, to direct that story to life, where this weekend it debuts at Chez Bushwick, a local studio space operated by the choreographer and dancer Jonah Bokaer.
