Background: Anggun Cipta Sasmi (Indonesian pronunciation: [aNG'gun 'tSipta 'sasmi]; born 29 April 1974) is an Indonesian and French-naturalised singer-songwriter. Born in Jakarta, she began performing at the age of seven and recorded a children's album two years later. With the help of famed Indonesian producer Ian Antono, in 1986 Anggun released her first rock-influenced studio album, Dunia Aku Punya.
Context: Anggun was born and raised in Jakarta to a native Indonesian family. She is the second child and first daughter of Darto Singo, a Javanese writer, and Dien Herdina, a housewife from the Yogyakartan royal family. Her full name means "grace born of a dream" in Balinese. Despite being a Muslim, Anggun was sent to a Catholic school to receive a better elementary education. At the age of seven, Anggun began receiving highly disciplined instruction in singing from her father. She trained daily, learning various vocal techniques. To help further develop her career, her mother began serving as her manager, accepting singing offers and handling business concerns. At the age of nine, Anggun began to write her own songs and recorded her first children's album.  As a preteen, Anggun was influenced by Western rock music artists. At the age of twelve, she released her first official studio album, Dunia Aku Punya (1986). The album was produced by Ian Antono, an Indonesian rock musician. However, the album failed to establish her popularity. Three years later, Anggun achieved some fame after the release of the single "Mimpi"; the song was later ranked by the Rolling Stone Indonesia magazine as one of the 150 Greatest Indonesian Songs of All Time. Anggun's fame continued to increase with the release of subsequent singles, most notably "Tua Tua Keladi" (1990), which became her most popular hit in Indonesia. After a string of successful singles, Anggun released the studio albums Anak Putih Abu Abu (1991) and Nocturno (1992). The former earned her the Most Popular Indonesian Artist 1990-1991 award.  In 1992, Anggun began a relationship with Michel de Gea, a French engineer, whom she had met the year before in Kalimantan while touring. The couple married, despite a rumoured objection by Anggun's family, reportedly because they felt Anggun was too young . Georgea later became Anggun's manager. The following year, Anggun became the youngest Indonesian singer to found her own record company, Bali Cipta Records, and took complete creative control over her work. She produced her final Indonesian studio album, Anggun C. Sasmi... Lah!!! (1993), which yielded the number-one single "Kembalilah Kasih (Kita Harus Bicara)". By age nineteen, Anggun had sold over four million albums in Indonesia. She began to feel dissatisfied with her success in her country and began considering an international music career. Anggun later recalled: "[By the time] I was 20, I'd made five albums. I'd built my own record company. I'd produced my last album and produced some Indonesian acts as well. And I said to myself: 'I'm tired! I cannot achieve more than I already have. There's no challenge anymore'."
