"''''Strobe Light'''' was [http://www.nin.com/pub/strobelight/ announced] on April Fools' Day 2009.

As part of the joke, the album was said to have been produced by [[wp:Timbaland|Timbaland]] and feature special guest singers such as [[wp:Jay-Z|Jay-Z]] and [[wp:Fergie (singer)|Fergie]].

* Head Like a Hole UK 12" vinyl release (1990)
