Tupac at Coachella -- Rises from the Dead ... Performs as Hologram [Video]

Tupac came back to life this weekend ... as a hologram ... and it was frickin' AMAZING!!!.

Pac was resurrected for the Coachella music festival in California ... and "performed" a couple of his greatest hits ... including "2 of Amerikaz Most Wanted" with Snoop Dogg.

We're told the crowd went INSANE ... especially when 2pac first appeared to the crowd ... rising up from the ground until he was standing on the stage.

The movements were remarkably lifelike ... grabbing his crotch and pointing his mic to the crowd like the good ole days.

At the end of his performance, a light shines on Pac ... and he dissipates into thin air.

Pretty insane ... especially for the "partiers" in the crowd ... who didn't realize it was a hologram.
