The 60th annual Newport Jazz Festival kicks off Friday. The three-day line up includes plenty of jazz greats you’ve heard of and many you probably haven’t. You may know the music of one of the festival’s Friday performers, Vince Giordano and the Nighthawks, from the HBO television series Boardwalk Empire. Giordano’s band creates the series’ authentic 1920s jazz soundtrack, and won a Grammy for it. He spoke with Rhode Island Public Radio’s Kristin Gourlay about his music and upcoming performance at the Newport Jazz Festival.
