Ault's book was my introduction, along with an amazing seminar taught by Robert Storr
, to alternative "spaces, places and voices" in New York between the 1960s and 1980s. (For those interested in further details, it was an expanded (somewhat way) after-the-fact catalogue for a 1996 exhibition at The Drawing Center
. The book was published in 2002.) If you have any interest in the subject this is the
place to start.
