Sometimes you have to sacrifice in the name of science. And Grizzly Bear takes that concept to a whole new level in this music video from their most recent album Shields. The Brooklyn band’s chill vocals and haunting melodies are contrasted against jarring scenes of self-mutilation. One second a man is collecting plant samples from field, the next someone is piercing their eye with a razor or poking their skin with a probing tool, all with the intent of observing the samples under a microscope. This is Human Biology class nightmarishly re-imagined by delirious art students.
