Dr. Dre had the closing spot at Coachella last night, bringing out Snoop Dogg, Kendrick Lamar, 50 Cent and Eminem during his set. But all of those guests are getting outshone by a computer program: Dre brought out a hologram of Tupac to perform "Hail Mary" and "2 Of Amerikaz Most Wanted." I don't even know how to feel about this. I hope Tupac's Tron family got paid a bunch of digital coin for this, and I wonder how much weed had to be smoked for this idea to be a reality. You can watch the Tupac hologram below, along with Dre's full set (which was pretty great actually).
