One of the craziest music-related moments of the year went down last night at Coachella and it came toward the middle of the festival-closing set by Dr. Dre and Snoop Dogg. During their performance, they "brought out" none other than 2Pac, who appeared in the form of a hologram. He proceeded to big up his still-living cohorts and performed "Hail Mary" solo before Snoop joined in for "2 of Amerikaz Most Wanted." It all makes for what's easily one of the most intriguing things we've seen in a minute, though we can't help but imagine where this could go next. Watch the performance above.
