Last night at Coachella Fest, Dre and Snoop had a special treat for those in attendance. Before anyone asks, no, they didn’t finally announce a release date for Detox. The surprise they had in store was something much more ethereal. None other than Tupac Amuru Shakur showed up to perform onstage with his former label mates. Well, it wasn't really Tupac, as the fallen Icon has been dead for some time. Instead, a holographic image of the most revered rapper of all time was projected onstage. After performing "Hail Mary" for the astonished crowd, it joined Snoop Dogg for a rendition of their duet "2 of Amerikaz Most Wanted."
