Hi,

This might be a tricky one, as I don't remember band name / song name / any lyrics / tune. Only remember the music video and also vaguely, since it was a few years ago

From what I can recall, in the music video
There was some kind of a party (birthday party?) with several children and a magician/entertainer? who turned them into wolves and in the end of the video they turn against their parents.

Hope this rings a bell to someone. Been dying to find it for a while
