It looks as if legendary singer Roy Orbison was back on stage, but how can that be? He died of a heart attack 30 years ago. What fans can see is a digitally recreated Roy Orbison. His guitar playing looks incredibly realistic. Even the fringe moves on his jacket. It took nine months to create a lifelike hologram of the late crooner and now, thanks to technology, the digital Orbison is now on a 28-city tour, starting in Los Angeles.
