Forms of Forgetting is a studio construction investigating memory/forgetting and attention/inattention as catalysts for formal development in long-duration sound work. An extension of Seth Cluett’s gallery-based practice and created out of a sequence of materials developed for performance, the piece is the culmination of two years of in-situ live experimentation. Part site-specific performance, part modular, mobile form, this work employs techniques that aim to explore the fallibility of sound memory as a component of saturated, immersive listening over substantial elapsed time.
