On April 16, 2012 the late rapper Tupac Shakur was brought back to life as a hologram (technically a 2-D video projection) and performed two hit songs "Hail Mary" and "2 of Amerikaz Most Wanted" with Snoop Dogg at The Coachella Valley Music and Arts Festival. A few days later, a sound record was uploaded to YouTube, in which you can hear a man shockingly claiming to be Tupac Shakur himself, saying that he's alive and laying down his opinion on the hologram. As ridiculous as it may sound to many, but this actually happened. Video courtesy of YouTube user DjOsoFreshVideos.
