Century is the first single to be taken from The Long Blondes second album "Couples". It was released on March 24, 2008, as a limited edition 7" single and digital download. The b-side to "Century", "The Unbearable Lightness of Buildings", was written specifically for Tate Modern as part of their 12-week-long Tate Tracks that was held at the beginning of April 2007. The idea was Tate invited The Long Blondes to walk around the gallery and find a work of art that would inspire them to write a track. In the end, it was Jannis Kounellis's Untitled that grabbed their attention. They said "Untitled caught our eye because we saw the stark industrial landscape and pictured ourselves within it".
