Amy Winehouse [SEP] Introduction
Amy Jade Winehouse (14 September 1983 – 23 July 2011) was an English singer and songwriter. She was known for her deep, expressive contralto vocals and her eclectic mix of musical genres, including soul, rhythm and blues and jazz. A member of the National Youth Jazz Orchestra during her youth, Winehouse signed to Simon Fuller's 19 Management in 2002 and soon recorded a number of songs before signing a publishing deal with EMI. She also formed a working relationship with producer Salaam Remi through these record publishers. Winehouse's debut album, "Frank", was released in 2003. Many of the album's songs were influenced by jazz and, apart from two covers, were co-written by Winehouse.
