Ylvis revealed the music video and song "a capella" on
I kveld med YLVIS on
TVNorge on January 5, 2016. In the music video, a small boy is bullied.
Ylvis brothers Vegard and Bård Ylvisåker head an a cappella group that attempts to save and galvanize the bullied child through their singing and joyful
facial expressions. They are able to defeat the bullies because they have the "scary" talent of being capable of "sing[ing] a song in any musical style". Caricaturing rousing a cappella songs, the song exploits frequent a cappella customs such as fake words, grinning "like you know Jesus personally", and a male
beatboxer. The song includes rock and rap, and a cappella members make
trumpet and
drum sounds. One of Ylvis' fictional words is "Boodelooap", a fictional Nigerian soft drink. Boodelooap is cherry-red and stored in a long tall bottle. ==Critical reception==
