What it means to be avant-garde is David Antin's third collection of "talk poems" published by New Directions. As in his earlier talking at the boundaries (1976), and tuning (winner of the 1984 PEN/Los Angeles Literary Award for Poetry), Antin's brilliant improvised disquisitions at once challenge readers' expectations even as they instruct and entertain. A poet, performance artist, art critic, and professor of visual arts, Antin, since his college days in New York in the '50s, has been at the cutting edge of the avant-garde. The avant-garde? Yes, if by this is meant not an image of fashion but the place where art and life intersect, imparting to both a greater urgency - if is meant the place where experience and knowledge find their deepest expression, where the idea of a universal language can find shape, where the price of art is itself, where the fringe is the very center of existence.
