Parody

A parody is an imitation of the style of a particular writer, artist, or genre with deliberate exaggeration for comic effect.

I particularly like this parody of Mumford & Sons as it starts of very realistic (making it seem as if it's the actual artists.) I thought the use of the close up camera work at the start really created mystery in not giving away the actors. The exaggeration of the artist's performance is very comedic and encouraged me to watch the actual Mumford & Sons video.
