Charles Bernstein: Avant-Garde Is a Constant Renewal.

The author presents a discussion of American poet Charles Bernstein and avant-garde literature, adapted from his introduction to the book "Sign Under Test: Selected Poems and Essays," edited by Ian Probstein. Topics explored include the history and aesthetic of poetry according to Bernstein, the opposition expressed by Bernstein to the 1950 essay "Projective Verse," published by fellow poet Charles Olson, and the structure and composition of essay-poems.
