It was only a matter of time since the 2012 Coachella Music Festival had a "hologram" version of deceased hip-hop legend 2-Pac, that that technology would be used for concerts to virtually "bring back the dead".

As was the case at the Rock The Bells 2013 concert. This year, during the Wu-tang Clan's set, they brought back Old Dirty Bastard in all of his 3D glory to perform 2 songs. Also revived in a hologram likeness was NWA legend, Eazy-E who materialized on stage with Bone: Thugs-N-Harmony.
