Back to Black

Mark Ronson produced "Back to Black" and co-wrote it with Amy Winehouse, shaping a track that drew on old school soul and the sound of 1960s girl groups. The song was recorded across three studios: Chung King Studios and Daptone Studios in New York City, and Metropolis Studios in London. Its production was noted for its Wall of Sound, and a documentary film about Winehouse, Amy (2015), features footage of the two working on the song together in March 2006.

Released by Island Records on 26 April 2007 as the third single from the album of the same name, the song was inspired by Winehouse's relationship with Blake Fielder-Civil, who had left her for an ex-girlfriend. The lyrics describe her going to "black", which the listener may take to mean drinking and depression, though some have wrongly assumed a reference to heroin; Winehouse's heroin use began only after her marriage to Fielder-Civil in May 2007. Critics praised her lyrics and vocal performance, and the song appeared on year-end and decade-end lists, including number 79 on Rolling Stone's 500 Greatest Songs of All Time. It peaked at number eight on the UK Singles Chart in July 2011, following her death, and Beyoncé and André 3000 later covered it for the 2013 film adaptation of The Great Gatsby.
