Jon B and Olivia headlined Brooklyn’s SummerStage Concert Series on Thursday night. Olivia (who opened the show) surprised the audience with the first-ever performance of her second single “Confident”. Fittingly she ended her set with the ladies anthem “December”, complete with a sing-along audience. Jon B tributed Tupac Shakur on his 40th birthday, with a performance of their collabo “Are U Still Down”. After 17 years in the game, Jon had the audience reminiscing on old times, as he performed hit after hit.
