Tupac Shakur performed onstage with Snoop Dogg at the Coachella concert. That Tupac has been dead since 1996 was not an issue. Thanks to technology a holographic likeness of the rapper was used. The lifelike hologram uses the same technology used by the musical group Gorillaz at the 2005 Grammys. Snoop Dogg joined the hologram onstage to perform a duet.
