Dead rappers Eazy-E and Ol' Dirty Bastard have been resurrected onstage as holograms of the late performers at the Rock the Bells festival.

The Rock the Bells 10<sup>th anniversary festival tour kicked off in San Bernardino, California with special "appearances" by the late NWA and Wu-Tang Clan members thanks to the special 3D hologram technology.

Tupac Shakur appeared onstage as a hologram to "perform" alongside Dr Dre and Snoop Dogg's 2012 headline Coachella slot.

Performing with Bone Thugs-N-Harmony, fellow NWA member DJ Yella appeared on stage to introduce the hologram of Eazy-E, who then went on to perform the tracks Straight Outta Compton, Boyz-n-The Hood and his Bone Thugs-n-Harmony collaboration Foe Tha Love of $.

The hologram even greeted the crowd, opening the performance by saying "What's up LA? Make some m***********g noise".

The NWA rapper died in 1995 at the age of 31 after he was diagnosed with Aids. The hologram's performance at the Rock the Bells festival marked what would have been his 50<sup>th birthday.

A hologram of former Wu-Tang Clan rapper Ol' Dirty Bastard also performed with the remaining members of the New York rap group during their headline slot.

The rapper died from a drug overdose four months after Wu-Tang Clan performed at the same festival in 2004.

The hologram performed the track Shame on a N***a from the band's Enter the Wu-Tang (36 Chambers) as well as his track Shimmy Shimmy Ya.
