New film in New York Close Up: Artist Erin Shirreff discusses sculptor Tony Smith as an inspiration for a pair of works: her first video work, Sculpture Park (Tony Smith) (2006), and her first public sculpture, Sculpture for Snow (2011). The latter was commissioned by Public Art Fund for their exhibition, A Promise Is a Cloud (2011–12), at MetroTech Commons in Downtown Brooklyn.
