Boomerang, recorded in a television station in Amarillo, Texas, used a delayed audio feedback system with two tape recorders and headphones. The set-up is intended to focus on thought processes as they are apprehended and verbalized. Nancy Holt wears the headphones, allowing her to hear her voice, both as she speaks, and a few seconds later, through the headphones and the audio feedback system.

In the tape, Holt explores the relationship between the generation of thoughts and the response to the thoughts already put into words as they revolve back and re-enter her processes of thinking and verbalization.
