The Rock-afire Explosion Movie Trailer

according to Wikipedia...
The Rock-afire Explosion was an animatronic robot band that played in Showbiz Pizza Place restaurants from 1980 to 1991...The stage was designed to be life-sized. Unlike many small novelty animatronic shows, the Rock-afire was designed to take up the entire length of the showroom. The stage was split into three sections, with the band in the center section and other characters on the two side sections each with separate curtains. Differing from their main competitor (Chuck E. Cheese's), the characters could mimic playing real instruments and had realistic facial expressions due to the use of latex masks (as used in Disney animatronics) as opposed to fabric and foam. The show also used a large amount of props and stage lighting effects which heightened the amount of perceived movement on the stage.
