You’ve heard a cappella songs that are done by one person using multiple voices (Dokaka, Petra Haden, and most recently, George Hrab), but this one adds a very cool visual twist:
François Macré – Thriller (reprise A'cappella 64 pistes)
The singer, François Macré, managed to record each of his tracks in video as he sang them, and arranged all 64 parts visually, so you can see each of the different tracks used for the song. It’s mesmerizing – and even though you know what to expect by about halfway through the song, you can’t turn away in anticipation of the Vincent Price bit.
Big thanks to Jeff U. for telling me about this!
