Dove Bradshaw has been a major proponent in the development of the artistic concept of indeterminacy. Her works combines unstable materials with traditional ones, setting off a metamorphic process. This process changes the appearance of her art over time; thus, time is a creative factor in her art as much as the materials themselves. This is the first extensive critical analysis of her work. Thomas McEvilley reviews Bradshaw's work from the perspectives of art as event and object, including descriptions of her collaborations with Merce Cunningham and John Cage. A conversation between Cage and McEvilley on Bradshaw' work and themes is included.
