News of the appearance was let slip by Toby Vogel, an events visual projections specialist who has worked on Gorillaz' live performances before, at the final of the Global DJ Challenge in South Africa. When asked by a journalist what he was up to next, Vogel replied: ""I'm creating three-dimensional holographic projections of Gorillaz live on stage for the Grammys". This was reported on an internet site here.
It is unclear what kind of appearance Gorillaz will be making (whether it will be a performance of a song or not). The Grammy website has not announced Gorillaz as performers so far, but full details of the show have yet to be released. The Grammy Awards take place on 8 February and will be shown at 8PM ET on CBS in the United States.
