Moore St between Bogart and White Sts, Bushwick, Brooklyn. Subway: L to Morgan Ave. The fourth annual Roberta’s-sponsored bacchanal brings elevated snackage and live tunes to the pavement outside the locavore hang. So it seems fitting that Queens-based rapper and goumand Action Bronson will be running a food truck and headlining the entertainment too. On the sonic front, he’s flanked by Travis Egedy’s electronic-pop project Pictureplane, self-described “Detroit trap-pop” duo Jamaican Queens, regular Roberta’s party-starters Tiki Disco and a host of others across multiple stages. Bronson will be doling out grub alongside stands from Crif Dogs, the Brooklyn Star, Yuji Ramen and more, while the host venue cranks pizzas out of four “ovens of doom” (10 percent of pie sales will benefit St. John’s Bread and Life, which provides meals to hungry New Yorkers). If—between the food, drink, music and prime hipster-watching—you somehow find yourself with nothing to do, check out the skate and Double Dutch demos and mug for the camera at a photo booth.
