The late Amy Winehouse's rich voice and her mixture of pop, jazz and soul stylings combined to create a musical sensation that mesmerized audiences. In 2003, at age 20, she released her debut album, Frank, which garnered a nomination for the UK's coveted Barclaycard Mercury Prize in 2004. Winehouse's sophomore effort, 2006's Back To Black, catapulted her to superstardom. The album netted five statues at the 50th GRAMMY Awards, including Best New Artist and Record and Song Of The Year for the Top 10 hit "Rehab." Winehouse's GRAMMY debut set a record for the most wins by a female British artist in one night, a mark that was ultimately broken by Adele in 2012. As her popularity soared with music fans, Winehouse grappled with her own addictions in private. On July 23, 2011, Winehouse was found dead in her London apartment. The cause of death was later cited as accidental alcohol poisoning. She was 27 years old. In February 2012 Winehouse won a posthumous award at the 54th GRAMMY Awards for Best Pop Duo/Group Performance for "Body And Soul" with Tony Bennett.
