"Book-ended by Cage's 4'33'' and Warhol's a: a novel, by 'silence' and 'glossolalia', Liz Kotz's text tracks a hitherto uncharted trajectory in what she terms "the turn to language" in vanguard art practices of the 1960s and 70s. Kotz's nuanced probing of linguistic operations serving instrumental or instructional ends and/or deployed as material entities illuminates an impressively wide range of works in various fields from experimental music and poetry, to the visual arts. Acutely attentive to that era's displacement of conventional categories, she constructs a network of cross disciplinary readings that freshly parses the interrelationships of Fluxus, Conceptual, performance and post-minimal art works with concurrent disciplines."--Lynne Cooke, Curator, Dia Art Foundation
