Tupac Shakur has been dead since 1996, but thanks to some new technology he was brought back to life in hologram form for the Coachella Festival finale starring Dr. Dre and Snoop Dogg in Southern California yesterday.

During  Dre's 70 minute set concert goers were stunned and silenced when Tupac first appeared on stage and said "What up, Coachella?", the hologramed  Pac traded rhymes with Snoop Dogg, on "Come With Me," "Hail Mary," and "Gangsta Party."

Not since R2-D2 delivered the message to Princess Leia from Obi-Wan Kenobi in Star Wars has the hologram been so cool.  *WARNING* the following video is NSFW, lots of dirty language, but would you expect anything less.
