From the video info:
Here is a remake of the "Thriller" song that I've entirely recorded with my own voice, using 64 A'cappella tracks. There is therefore no instrument, synthetizer, beatbox, or even to sampler, but only the sound of my voice livened up with Reverb and slight Chorus on certain tracks. Regarding looping parts, I've simply used the "looping" technique. Moreover, in the whole piece (which contains several thousand notes), I transposed 8 notes, which were impossible for me to sing in high-pitched. Because of my tessiture, I also must have resigned myself to sing certain parts in head voice, more particularly on the track corresponding to Michael Jackson's solo vocal.
I've accomplished this non-commercial project at home, only with a mobile PC, microphone, headphones and webcam - in nearly 350 hours. It's just an artistic challenge, accomplished during my hours of free time, whose purpose is to make smile my close circle and net surfers. Nonetheless, I'll be happy to record in professional studio, original songs with this technique, if a label was interested to work with me on a SP or LP entirely based on this innovative concept of "Massively Multitracks A'cappella".
