"Declare Independence" was released as the third single from "Volta" on 1 January 2008. The video, directed by Michel Gondry (his seventh video with Björk, and the first since 1997's "Bachelorette"), was premiered on AOL on 6 December 2007 and on Channel 4 in the UK on 13 December 2007. A making-of was made available on November 29, 2007. The video shoot took place on 11 October 2007 in New York City. Unlike the first two singles from "Volta", the single has a physical release in the form of two 12-inch vinyls, a CD and a DVD.
