"Declare Independence" was originally meant to be released as the second single from "Volta" in August 2007, but the previously-planned video shoot for "Declare Independence" with Michel Gondry in London was postponed to due to Björk's busier than expected promotional schedule. The deadline for the music video contest for "Innocence", then slated as the third single, was then brought forward a month to 10 June 2007 so as to provide a finished video able to coincide with a July 2007 release originally planned for "Declare Independence". The limited edition "multiformat" box set consists of a sticker-sealed fold-out box with five colored nesting boxes containing two 12" vinyl singles, a CD and a music video DVD in colored paper sleeves. A digital release accompanied the physical release on the same date.
