Clear Air is a collaborative sound-and-text performance by Ben Estes and Ben Vida, taking place in the Felix Gonzalez-Torres galleries at Dia Beacon. In Estes’s text, performed by Estes, Tom Cole, Randy Danson, and Jane Gregory, formless voices of human awareness travel down beams of light, hang still in midair, appear as shadows on furniture, or are broadcast on radio waves; they may be the voices of spirits caught between worlds. Drawing on spiritualism, concrete poetry, and Quakerism, Clear Air behaves like a text written in the ether. Giving sonic form to Estes’s translucent streams of thought, composer Ben Vida contributes a hypnotic electronic music score. The arrangement of voices and electronics acts to produce an atmosphere of ambient language, abstracted narrative, and vocal texture.
