ASK THE SAND is the journey of a father and a son in search of the utopian city of Arcosanti, city of the future built in 1970 in the Arizona desert by the Italian architect Paolo Soleri (1919-2013), a student of Frank Lloyd Wright. A journey that is also a father's birthday gift to a son who becomes a man. Soleri is one of the most important characters of the twentieth century, still forgotten, and his life is told with the virgin eyes of an aspiring architect with very open antennas about what is happening in the world and what each of us can do to help improve it.
