LAS VEGAS - The late King of Pop Michael Jackson was back on stage -- as a hologram -- performing at the Billboard 2014 Music Award event Sunday in Las Vegas.
Jackson, or rather his hologram, sang and moonwalked to "A Slave to the Rhythm" dressed in a gold jacket, white t-shirt and red pants, along with a live band and dancers onstage.
The song was recorded in 1991 and released as part of the album "Xscape," which includes previously unreleased Jackson tracks.
Jackson's "performance," a tightly-held secret up to the last moment, required a year of work from 104 artists and technicians, according to organisers.
Jackson, 50, died in June 2009 after taking an overdose of the powerful sedative propofol. "Xscape" is his second posthumous album.
