In 2018, Maria Callas rose from the dead. During a series of tours dubbed Callas in Concert, local orchestras performed with a three-dimensional hologram of the departed diva as she re-sounded arias of her past. This virtual manifestation of Callas put on a convincing show. Listeners were struck by the quality of the diva's voice – ‘from heart-breaking vulnerability to imposing strength’ – and marvelled at foley effects such as the clicking of her heels and rustling of her gown. Notably, however, the performance fell victim to repeated technical failures. In Chicago, a glitch caused her final encore to end prematurely; in Blacksburg, Virginia, audience members were distracted by the transparent nature of the hologram, which gave Callas an ‘especially ghostly appearance’. The performances set the operatic sphere atwitter with questions of ethics and taste, debates over classical music's obligations to the living and devotions to the dead. Anthony Tommasini likened the performances to a grand séance, an act of operatic necrophilia. Catherine Womack interpreted the spectral shows as a sign that ‘in the twenty-first century, living and breathing are not prerequisites for a successful performing career’. However, as Deirdre Loughridge, Gundula Kreuzer and Gabriela Cruz demonstrate in their monographs, Callas in Concert is not a phenomenon unique to the twenty-first century. Indeed, the authors show that technologically mediated resurrections of the dead, operatic appeals to nostalgia, and illusion-busting technical failures are instead part of a long operatic tradition, one which began well before the holographic revitalisations of Maria Callas.
