Best Known for the Fanservice: The video for "Pagan Poetry" sticks out in memory because it features rotoscoped scenes of Björk and Matthew Barney having unsimulated sex. The piercings are also hard to forget.
To elaborate: "Hidden Place"'s video is a close-up shot of Björk's face as a colorful mucus run through her eyes, nose and mouth. "Pagan Poetry"'s controversial video is a highly stylized sex tape of herself and her partner with a bonus at the end as half-naked Björk expresses herself in front of the camera with her body all pierced with pearl. "Cocoon"'s shows Björk in a 'naked' bodysuit playing with red thread extruding from her nipples with a few of squicky shots.
On February 11, 2010, her longtime friend and collaborator Lee Alexander McQueen committed suicide. Björk performed "Gloomy Sunday" in his memorial. If this isn't enough to make you a teary mess, the performance itself will be.
