Watch The Ol' Dirty Bastard Reunite With The Wu-Tang Clan In Hologram Form

The RZA, the GZA, the Ol' Dirty Bastard. Together again, "thanks to modern science."

At last night's Rock The Bells festival in San Bernardino, Calif., the Ol' Dirty Bastard joined the Wu-Tang Clan in hologram form to perform "Shame On A Ni**a” and “Shimmy Shimmy Ya."

ODB, who died in 2004, was the second hologram to appear at the festival. Easy-E, who died in 1995, performed on Saturday night.

"Thanks to modern science, we're able to bring to you... the greatest hip-hop brother to ever touch the mic," members of the Wu-Tang Clan announced.

In typical Dirt McGirt fashion, his hologram disappeared quickly, with a spin into air.

There were strict rules.

Earlier in the weekend, a hologram of Easy-E joined Bone Thugs-N-Harmony, which was also awesome.

Easy-E's hologram performed "Straight Outta Compton," "Boys-N-The Hood," and "Foe Tha Love of $."
