NPR’s All Songs Considered celebrated its Sweet 16 with a sold-out crowd at the 9:30 Club on Wednesday night. In addition to the announced performers of Sharon Van Etten and Dan Deacon, special guest performers included the soulful sounds of The Suffers, the one-man dynamo that is Kishi Bashi, the first person to perform a Tiny Desk Concert, Laura Gibson, and Glen Hansard. Hansard’s cover of Leonard Cohen‘s “Sisters of Mercy” was the night’s first crowd sing-along, and his cover of David Bowie‘s “Ashes to Ashes” brought the first tears to the crowd’s collective eyes. There was confetti, video tributes, cake, and tons of balloons, as well as a mega dance party courtesy of Deacon. All Songs Considered‘s hosts, Bob Boilen and Robin Hilton, who hosted the night, really know how to throw a party.
