Incredibox was created by the French studio So Far So Good and first released online in 2009 as a beatbox loop game where players drag sound icons onto animated characters. Version one, later known as Alpha, included hidden bonus tracks that played as short animated songs when specific combinations were found. This first bonus built around its choir voices became a favourite in fan recordings, YouTube mixes and soundboards, shared separately from the game because the choral hook works on its own as a short dramatic sting.
