We have to thank Jay Z for bringing this into the overall thinking. He worked with us on the second party in the movie. The first party is a gaudy, rich, Venus flytrap of a celebration designed to attract Daisy's interest by physically bringing the entire city of New York to Long Island. The second party is one that Daisy does attend, but at this point in the story, we were looking for a musical direction that alluded to darker things beneath the surface. We were looking for a song that would speak to the almost 'Sid and Nancy' addictive love that Gatsby and Daisy have found themselves re-engaging in. Everybody knows the Amy Winehouse version of this song, and I think this is a very interesting interpretation. It plunges you further into this particular kind of lovesickness. I think it works very well in the film, where it blends between a jazz recording that The Bryan Ferry Orchestra did and the version on the album with Beyoncé and André 3000. That combination helps to deepen the resonance of what the song is telling us.
