    Looks like there is some transparent fabric in front of the stage their devices are doing a rear projection onto the fabric. Notice that even though the camera wobbles a little it doesn’t actually move to the left or right which could mess up the effect. Looks like you have to view this one from only a certain angle for it to work.
    Awesome stuff though.

    The program that they are using is made by a company called Serato. You can see it running on the laptop by the turntables. It is originally a DJ program that allowed you to play any digital audio file and manipulate it as if it were on the record. The “records” that the software comes with have a tone on them to let the software know where the record is and how it is being manipulated. The newer version of this software allows video to be linked to the audio files, it also allows for midi controlled video. That is where the digital drum set comes in. It is a MIDI output.

    While there is no post production being done there is an amount of preproduction. There are several video/sound files being loaded throughout the performance. Each sound has an accompanying video. The drumkit head sounds were filmed direct and the turntable head sounds were filmed while the guy probably rotated in a chair. The scratch rocks the video back and forth and gives the impression that it is spinning on the record.

    The guy above me is correct about projecting the video on a transparent screen. It is a similer effect that has been used in the Haunted Mansion at Disney World for a long time. It must be viewed from a certain angle for everything to line up right.

    I hope I didn’t ruin anything for anyone but you asked for guesses as to how it was done.

    My guess is that they are using the Musion Eyeliner system to display the “holograms”. The fictitional CG characters of the band “Gorillaz” performed onstage with Madonna at the Grammys in 2006 using this technology.

    It’s really simple. I don’t understand the hype over the projection system. The software that enabled the performance and forethought that went into presenting it is more impressive.

    “Musion Eyeliner” is the “Pepper’s Ghost” technique (originally the Dircksian Phantasmagoria) under another name. That fact that they re-packaged an existing technique and don’t openly credit the original creator(s) has more than a few people upset.

    That said, it’s use in this video is outstanding.
