In his three Like a Hole in the Head videos, young Sydney artist Robin Hungerford dons big papier-mache pinata heads, which he attacks with hammers, knives, electric drills, and hedge clippers, pulling out brains, blood, and viscera until nothing’s left. Like a Hole in the Head is hysterical, simultaneously engaging us in its sadism and its pathos. Self-harm has never been so much fun.
