So, this has got to be the dopest futuristic show ever! We're talking about on a "Back to the Future" level. Snoop Dogg took the stage at Coachella Sunday night, but the show was stole with an appearance from dearly departed 2pac. Well he may not be here in flesh but technology has risen the famous rapper into a hologram. Pac even shouted out Coachella during his set. Will this new technology be a way for us to connect with past melodies from our favorite artists??
