Part of the Rock Hall's Author Series, tonight's lecture at the Rock Hall will feature Gayle Wald, who'll discuss her book Shout, Sister, Shout!: The Untold Story of Rock-and-Roll Trailblazer Sister Rosetta Tharpe. It's a particularly timely event since Tharpe will be inducted into the Rock Hall this year. Wald's presentation will include video, audio and images. Senior director of library and archives Andy Leach will lead a discussion after the talk. The event will conclude with an audience Q&A and book signing. It starts at 7, and admission is free.
