Late rappers Ol' Dirty Bastard and Eazy-E will rise again to 'perform' at the upcoming Rock the Bells hip-hop festival. The pair will return from the grave in the form of holograms at the event, with ODB appearing alongside his former group the Wu-Tang Clan, while Eazy-E will perform virtually with Bone Thugs-n-Harmony. ODB performed at the first festival in 2004, just months before his death from a drug overdose. Eazy-E lost his battle with AIDS in 1995. Their planned appearances come after Dr. Dre won huge acclaim for bringing Tupac Shakur back from the grave at the Coachella music festival in California in 2012. The festival will tour the U.S. in September and October (13), with dates in California, New Jersey and Washington, D.C.
