"Songs for Sabotage," the fourth iteration of the New Museum Triennial, is less an expo of subversive acts documented than a cumulative call of desperation. The show’s titular “sabotage” is mostly limited, in the hands of the twenty-six artists and collectives selected by New Museum curator Gary Carrion-Murayari and the Institute of Contemporary Art’s Alex Gartenfeld, to expressions of dissent. A low bar for treason, perhaps, but one the United States’ current administration seems to endorse as it attempts to silence and discredit its critics as “unAmerican." Their right to revolution largely abdicated, these practitioners call out injustice but stop short of direct action. . .
