Tupac Shakur is alive.

Well, not really. But that didn’t stop the late rapper from making an appearance during Dr. Dre and Snoop Dogg’s performance at Coachella Sunday night via hologram.

If you haven’t yet seen the performance online, Snoop introduces Shakur before an eerily accurate digital representation of the rap legend appears on stage, complete in saggy jeans, construction boots and mic in hand.

The hologram of Shakur walked around the stage, preening for the crowd and talking with Dre and Snoop, even asking the crowd, “What the f— is up, Coachella?!” before starting to rap.

The hologram performed “Hail Mary,” “Gangsta Party,” and “2 of Amerikaz Most Wanted” with assistance from Dre and Snoop before dissipating into a burst of light.

The stunt was creepy, unsettling, maybe a little disrespectful, and yet still entirely enjoyable.

It was stunning to see such a life-like version of Shakur on stage, with rap pillars Snoop and Dre, sixteen years after his death (even if we were robbed of Shakur and Dre trading verses on “California Love”).

It was certainly a cool experience for everyone at the festival, and I enjoyed seeing Shakur “perform,” but this technology still concerns me.

Holograms are nothing new (remember those ridiculous hologram interviews on CNN a few years ago?) but this is the first time to my knowledge they’ve been used to bring someone back to life for a performance.

Let’s be careful not to overuse this technology. I don’t need to see Lennon and Harrison rise from the grave to join Starr and McCartney on stage (not that I think that would ever happen, but still).

As cool as this technology is, using it to have someone perform posthumously seems unethical. When a performer can’t give his or her permission to perform, I can’t truly approve of the stunt in good conscience.

What I’m concerned about are the people who own life rights to people like Jimi Hendrix, Amy Winehouse or Kurt Cobain and might be willing to profit from the selling of their holographic likeness.

Then again, who am I kidding? If the Hendrix-Winehouse Hologram Experience is performing down the street, I’ll see you there.
