Holograms are going mainstream, with the future full of possibility

New York

CONCERT promoters hoping to bring out legends such as Whitney Houston, Billie Holiday and Elvis Presley used to face an obvious problem - the singers are dead. But with rapid advances in technology, those stars and many more are returning to life through holograms, the three-dimensional light projections that have opened new frontiers for the live music and other industries.

The hologram boom began in April 2012 when Coachella, one of the most influential music festivals, resurrected slain rapper Tupac Shakur in a headlining set by his former collaborators Dr Dre and Snoop Dogg.
