Lowdown Hudson Blues Festival

This year’s get-down goes a long way to honor the genre that spawned it, while pushing its well-worn boundaries. Sharon Jones and the Dap-Kings appear, touring behind a recent effort, Give the People What They Want—a title that encapsulates the fun-loving group’s mission. (The album’s release was delayed so that Jones could get treatment for cancer.) No BS! Brass Band, Robert Cray, John Hiatt and James Carter are also on the docket.
