at SFlix. Signals Through the Flames is at once a history and a celebration of the Living Theatre. Founded in the late 1940s by husband-and-wife performers Julian Beck and Judith Malina, the Living Theatre was for many years the predominent American outlet for the avant-garde movement. There were occasional self-imposed exiles to Europe in the 1950s and 1960s, but the group returned full-force during the Aquarius Age to entertain a new generation of theatregoers.
