Alive From Off Center was PBS's pioneering TV series that featured experimental video and performance pieces by artists like Ann Magnuson, the Brothers Quay, Jonathan Demme, Bill Irwin, and Laure Anderson. For me, the program, which aired between 1985 and 1996, was a wonderful introduction to many avant-garde artists and filmmakers. Above is Laurie Anderson's "What You Mean We?" that first aired on September 6, 1986.
Here's a New York Times article about the episode from the time: "TV: Laurie Anderson Performs"
