An original flyer announcing John Cage's lecture/performance, 'Indeterminacy - new aspect of form in instrumental and electronic music', at the Living Theatre, New York, January 25, 1960.

Printed letterpress in black on off-white stock, recto only. 28x21.5cm. Near Fine.

The performance consisted of Cage reading from a series of stories, each one lasting no more than a minute, some written by himself, some collected from friends and colleagues, others are Zen stories, accompanied on piano by David Tudor. The flyer advertises the recently released Folkways recording of "90 of john cages stories…on sale in the lobby of the living theatre". Cage subsequently incorporated a number of the stories as interludes throughout his first collection of writings, 'Silence' (1961).
