Oracle is an EP by American drone metal band Sunn O))). The track "Orakalum" was recorded as part of a collaboration between the band and sculptor/installation artist Banks Violette for an exhibit at London's Maureen Paley gallery. The exhibit took place in two rooms: one with a black stage where the band recorded "Orakulum" with Attila Csihar locked inside a white coffin, and one with a white replica of the band's stage set up (including amps and guitars) cast out of salt and resin with a destroyed black coffin. The audience was locked outside for the performance and let inside after the band left "to generate a feeling of absence, loss and a phantom of what was."
