A cause of death has not been determined.
Amy Winehouse released her first album, Frank, in 2003 on Island Records. Songs like “F*ck Me Pumps” and “My Bed” (which shares the same sample as Nas’ “Made You Look”) earned her a legion of fans and critical acclaim. Her follow up album, Back To Black, featured more production from Nas collaborator Salaam Remi and Mark Ronson, spawning the hit “Rehab.”
The Grammy Award winning song was autobiographical in nature, since Winehouse had on-going issues with drugs and alcohol.
Several days ago Winehouse performed with her god daughter Dionne Bromfield at the iTunes Festival at the Roundhouse in Camden. This may be her last recorded performance. [source]
