It is a very interesting experience to listen to Richard Serra speak in such controlling language and then the other narrator continues ("...as you exit this end, please turn to the left," etc.) as we view the very controlled spaces that Serra has built within the confines of the city structure. I view this as a metaphor for societal, psychological, and group restrictions that we at first unknowingly accept and then react to in myriad ways. Here is one place where art fits the term evocative.
