Purely History on Instagram: "In April 2012, at the Coachella Valley Music and Arts Festival, Snoop Dogg performed on stage with a holographic projection of Tupac Shakur. The lifelike hologram was created by Digital Domain and AV Concepts, and it surprised the audience by making Tupac appear to perform alongside Snoop and Dr. Dre. This moment became one of the most talked-about performances in festival history and helped popularize the idea of using holograms for live shows."
