Since moving to New York City in October 2005, Gregory has been primarily working with electro-acoustic ensembles and dancers. His unique approach towards the saxophone is informed by the texture and tones of feedback/electronic music as well as a deep appreciation for space and natural sound. Currently he is working on two large scale multi-media projects: a series of performance and visual compositions that explore the liminal nature of the horizon and the phenomena of twilight and, in collaboration with Ann Adachi and Corrie Befort, a mnemonic map of Tokyo using field recordings, video projection, text, improvised music, and dance to explore memory and the perception of space.
