Snoop Dogg and Tupac Shakur

Tupac Shakur's "appearance" at Coachella was leaked a few days before the festival, but it was still a shock to see the deceased rapper onstage, uttering phrases he had never actually said during his lifetime. He "performed" two songs, "Hail Mary" and "2 of Amerikaz Most Wanted," and it looks like the success of the stunt will lead to a tour with Dr. Dre and Snoop Dogg.
