Primetime television returns in full swing next week, with the premieres of both new and returning shows on all of the major networks. Today: What to expect musically out of this fall’s TV lineup. Plus: The story of a devastating 1940 fire at The Rhythm Club in Natchez, Mississippi – and the music it inspired. And: Singer-songwriter and electric guitarist Annie Clark performs as St. Vincent. She joins us to play songs from “Strange Mercy,” a new album out this week.
