John Giorno (1936-2019) lived and worked in New York City. An iconic character from Andy Warhol films, John Giorno drew inspiration from the free appropriation of Pop Art images and and incorporated sound capture of vernacular language from commercials, television, newspapers, and the street into his art.
Referring to his work, Giorno has said, "I love the faults in stones. What I like are the older stones that have been abused. These are from the Delaware Water Gap - they have been rattling around for thousands of years. It's like a graveyard of three Ice Ages. These bluestones have been battered by the Ice Age. When the bluestone was being formed, the granite was inside. So, it's like the letters in the granite are peeking out."
