Genre and ground-breaking architect Paolo Soleri remains relatively unknown outside of architectural circles, but his legacy as an artist, builder and urban theorist is staggering. Narrated by actor-activist Peter Coyote, Aimee Madsen’s documentary takes a close look at Soleri’s origins and lifelong labor of love– the futuristic city of Arcosanti which Soleri sets in the unforgiving desert outside Phoenix, Arizona. Inspiring a near cult-like following rivaled only by the passionate devotees of the architectural giant Frank Lloyd Wright, Soleri’s city continues to grow piece-by-piece long after the death of its creator. Soleri is the most interesting architect you’ve never heard of.
