The song was released in 1988. The 45-degree tilt seen in the MV relies on a rope tied around the actor's waist. Of course, the rope is processed later in the MV and the audience cannot see it. This method is not realistic in a concert. Because a rope tied around the waist is simply impossible to set up and take down during a live performance. Second, the ropes installed in advance restricted the dance movements of the actors’ arms and bodies. So Jackson and his assistant invented a special pair of shoes. In 1993, Michael applied for a patent for the astonishing 45-degree forward tilt patent number (US5255452). The patent title is "The Illusion of Escape from Gravity." When Mike needs to perform a stunt, MJ and the backup dancers will approach the "special area" of the stage. Usually the lights in this area will be very dim at this time. The "gangster" played by the staff will immediately appear and perform for a few seconds with explosives in hand. Distract the audience's attention and give MJ time to prepare. When MJ is ready, the "special area" will light up. Mike tilted forward 45 degrees in one go! ! The key detail lies in MJ's special pair of shoes. As you can see from the picture, the heels of the shoes are mechanically connected to the stage, which can firmly fix the supporting points of the body. Technical details: This method overcomes the shortcomings of the rope system and allows the concert to proceed coherently. This achieves the visual effect of the body's center of gravity exceeding the support point. At the same time, the stage's "grabbing hook" system can be accurately retracted and retracted at the right time through the control of precision instruments to achieve the purpose of not being discovered. Special reminder: Even so, this action is not something ordinary people can do, because in order to complete this incredible action, in addition to advanced instruments, it is also inseparable from the hard training, careful rehearsal and running-in of Mike and the actors. Inseparable from strong back muscles and body balance control!
