In 2012, the rapper Tupac Shakur performed in the top slot at a major music festival — an event only notable because he had died 16 years earlier. The performance was made possible by a 21st-century digital upgrade of a 19th-century stage illusion called Pepper’s Ghost, and it ushered in a trend of creating and presenting similar “hologram” performances of posthumous pop stars. This article offers an explanation of what is seen in such a performance, examining the simulation of 3D video imagery designed to veil its mediation in order for its subject to appear unmediated, present, and “real.” Ultimately, I claim that these illusions are contemporary séances — a revival of historically spiritualist practices but one in which what is conjured is actually the deceased’s previously existing performing persona, as the concept has been extended by Philip Auslander. This cultural entity (distinct from the body and able to outlive it) is offered a new embodiment within a media system that restores the immaterial entity to the material space of the stage — a context previously off limits to the dead performer.
