“[I]magine a situation where the paintings of Rauschenberg or Bacon were taken down from galleries as soon as those artists died; where the novels of Saul Bellow were removed from the bookshelves, or the music of Stravinsky was silenced. … No other art form would accept for a second that death implied the possible death of an artist’s oeuvre. But what makes this a genuine issue for modern dance is the umbilically close connection between most choreographers, their companies and their work.”
