At this month’s First Saturday at the Brooklyn Museum, the theme is “Brooklyn Nature” but the evening’s offerings go beyond it. Along with company SoNoGlo’s nature-inspired dances, and a print-making workshop using natural elements, you can play with Andy Lin’s Self-Portrait photobooth, hear Cathy Erway read from her book, The Art of Eating In, and an open-mic edition of The Moth as the hip-hop and soul dance party gets down. Free tickets for some of the programming are handed out starting at 5.
