Tupac died in 1996, and no, he didn't rise from the dead, he appeared in "hologram" form, MTV News
Ed Ulbrich of Digital Domain Media Group Inc, the group responsible for creating the virtual Tupac which performed Sunday, told The Wall Street Journal
that Tupac appeared in a 2D image, and not really a hologram. Digital Domain Media Group Inc is also for making the virtual versions of Brad Pitt in 2008's The Curious Case Of Benjamin Button
"To create a completely synthetic human being is the most complicated thing that can be done," Ulbrich told WSJ.
Sources say that representatives for Dr. Dre and Snoop Dogg are in talks about taking the "new" Tupac on tour. One option being discussed is a tour that would feature the virtual Tupac with rappers such as Wiz Khalifa, Eminem, and 50 cent, MTV News
reports. Another option is a tour featuring Snoop Dogg, Dr Dre, and the virtual Tupac.
"This is not found footage. This is not archival footage. This is an illusion, and this is just the beginning, Ed Ulbrich told WSJ.
"Dre has a massive vision for this."
Tupac's mother Afeni Shakur watched her late son's performance via the internet. A rep for Afeni told TMZ
she was absolutely thrilled with the performance. She also called the experience "bittersweet."
Before going ahead with the project, Dr. Dre talked to Afeni to get her permission. As a thank-you, Dre made a donation to the Tupac Amaru Shakur Foundation.
