Visionary artist Laurie Anderson brings her incisive voice and boundless imagination to Tanglewood in The Republic of Love, an evening of music and storytelling that reflects on America’s past and present. Reexamining works such as Big Science and Language Is a Virus, and weaving in the words of Bob Dylan, Lou Reed, John Cage, Gertrude Stein, and others, Anderson — joined by the genre-defying ensemble Sexmob and other special guests — creates a concert that is provocative, intimate, and ultimately a celebration of artistic freedom
