"The City Wears A Slouch Hat" is an OTR drama combining a script written by Kenneth Patchen with live and recorded sound effects composed by John Cage. Every scene in Patchen's drama, narrated by "The Voice," is accompanied/interpreted by Cage's percussion / sound effects, creating an aural imagery that permeates every aspect of the imaginary city.
"The City Wears A Slouch Hat" is significant for several reasons. Both Patchen and Cage were major influences for the American avant garde movement. This work follows Patchen's experiments incorporating jazz music into his writing. For Cage, "The City Wears A Slouch Hat" was an experiment creating music from noise. Although a failure, "The City Wears A Slouch Hat" led to further experimentation regarding the technological future of music and the use of noise as sound source.
"The City Wears A Slouch Hat" is a collaboration between two leaders of the American avant garde movement, John Cage and Kenneth Patchen. Patchen (1911-1972), an American poet and novelist, was an important inspiration for the San Francisco Renaissance and the Beat Generation. John Cage (1912-1992) was the most influential and controversial American experimental composer of the twentieth century. Beginning in 1937, Cage promoted the use of noise to make music.
In 1941, The Columbia Workshop commissioned Cage to compose a radio play based on the text "The City Wears A Slouch Hat," by Patchen. Cage was to use sound effects to demonstrate his ideas about noise making music.  Cage's original 250-page score was written exclusively for electronic sound effects utilized as musical instruments.
Told his score was impossible to produce, Cage scaled back his vision to five percussionists, and live and recorded sound effects. Instruments included tin cans, muted gongs, woodblocks, alarm bells, tam tam, bass drum, Chinese tom tom, bongos, cowbells, maracas, claves, ratchett, pod rattle, foghorn, thundersheet, sound-effect recordings, etc. Script available here.
