“The closing of 38 Greene feels like the end of an era, partly because it reflects the threat posed by the gold-coasting of Manhattan to its alternative spaces — among them the excellent White Columns on West 13th Street. Now facing the ends of leases, profit-hungry landlords and the like, these spaces are seers. They have a nerve and flexibility absent from museums and commercial galleries. Their nurturing of non-mainstream artists and collectives is essential to a living art world.”
