Back to Black is the second and final studio album by English singer and songwriter Amy Winehouse, released on 27 October 2006 by Island Records. Winehouse predominantly based the album on her tumultuous relationship with then-ex-boyfriend and future husband Blake Fielder-Civil, who temporarily left her to pursue his previous ex-girlfriend. Their short-lived separation spurred her to create an album that explores themes of guilt, grief, infidelity and heartbreak in a relationship.
Back to Black was acclaimed by music critics, who praised Winehouse's songwriting and emotive singing style. The album spawned five singles: "Rehab", "You Know I'm No Good", "Back to Black", "Tears Dry on Their Own" and "Love Is a Losing Game". It has also been cited as being a key influence to the widespread popularity of British soul throughout the late 2000s, paving the musical landscape for artists such as Adele and Duffy. At the 2008 Grammy Awards, Back to Black won Best Pop Vocal Album and was also nominated for Album of the Year. At the same ceremony, Winehouse won four additional awards, tying her with five other artists as the second-most awarded female in a single ceremony.
