Infamous rapper Tupac was killed at the age of 25 back in 1996. Fortunately, his music lives on due to timeless lyrical rapping and undying fans. Audiences at the Coachella music festival in California were treated to a holographic performance of the rapper along with Dr. Dre and Snoop Dog (in the flesh). His hits Hail Mary and 2 the Americaz most wanted were performed. The insanely realistic appearance was done by combining actual live footage, wire framing and CGI as reported by Forbes (check it for more details). Regardless, looks sick.
