2PAC Performs at Coachella as Hologram

Snoop Dogg and Dr. Dre brought Tupac Shakur back from the dead for a showstopping finale to the first Coachella weekend.

Shakur appeared as a hologram on the festival stage after a tribute performance of his hit California Love and the late star 'teamed up' with Snoop on Ain't Nothin' Like A Gangsta Party after an eerie solo rendition of Hail Mary from beyond the grave.

The ghostly apparition drew mixed reactions from those watching the set online, with one fan calling it "wrong on so many levels" and others stunned by the Tupac trick, tweeting, "WTF!"

But most rap fans were thrilled, including the stars in attendance. Katy Perry tweeted, "I think I might have cried when I saw Tupac," while her pal Rihanna boasted: "TupacBACK unbelievable IWASTHERE STORY4myGrandKidz (sic)."

Estelle added, "TupacBack Yeaaaahhhh omfg ... Real tears" and actress Teresa Palmer declared, "Coachella could not be cooler right now."The duo also performed Dre's first solo single, Deep Cover (187), Nuthin' But a G Thang and a brief cover of House of Pain's Jump Around.

The rap superstars closed their 60-minute set with their classic hit Still D.R.E. and it was clear the reclusive producer/hitmaker had really enjoyed what one Twitter fan called "Epichella." He left the thousands at the festival with the line, "Coachella, I wanna say thank you for all the love over the years."

Taking to Twitter after his performance, Wiz Khalifa told fans, "(expletive) 2pac Ahhhhhhh!!! I Performed Wit Dr Dre And Snoop Dogg!!! Awww (expletive) Im So Happy To Be Alive. That Was The Best (expletive) I Seen In My Life! Thank Everybody!!! Snoop. Dre. Warren G. Pac. The Stoners. The Ratchet!!! Usher. 50 Cent. Coachella Was Life Changing!!!"

The weekend festival also featured headlining performances from The Black Keys, Radiohead, Florence & The Machine, Miike Snow, Noel Gallagher's High Flying Birds, M83, The Shins, Bon Iver, A$AP Rocky, Pulp and Arctic Monkeys.

The acts will repeat their performances and festival time slots at a second Coachella next weekend.
