Background: Li Lykke Timotej Zachrisson was born in Ystad, Skane; her mother, Karsti Stiege, was a photographer, and her father, Johan Zachrisson (stage name Zilverzurfarn), is a member of the Swedish punk-reggae band Dag Vag. The family moved to Stockholm when Zachrisson was a toddler and when she was six moved to a mountaintop in Portugal where they lived for five years. The family also spent time in Lisbon and Morocco, and winters in Nepal and India. She moved to the neighborhood of Bushwick in Brooklyn, New York City, for three months when she was 19.
Context: Li released her first EP, Little Bit, in 2007. Stereogum named her an artist to watch in October 2007 and described her music as a mix of soul, electro and "powdered-sugar pop". Li's debut album, Youth Novels, was released on LL Recordings in the Nordic region on 30 January 2008 and received a wider European release in June 2008. The album was produced by Bjorn Yttling of Peter Bjorn and John and Lasse Marten and was reportedly inspired by a previous relationship of three years. It was released in the United States on 19 August 2008. The album was released in the United Kingdom in June 2008, promoted by a performance of "Little Bit" on Later... with Jools Holland on 25 May 2008. Li performed live with a pared-down drum kit, a necklace made out of percussive instruments, a guitar, a bass and a microphone. Youth Novels was placed on many of the year's Best Of lists and saw Li sell out tours, including sets at festivals Glastonbury, Coachella and Lollapalooza. She appeared on Late Night with Conan O'Brien. She appeared on Swedish musician Kleerup's self-titled album, contributing vocals to the track "Until We Bleed". She also worked with Norwegian electronic duo Royksopp on their 2009 album Junior, contributing vocals to "Miss It So Much" and "Were You Ever Wanted". Li appeared on Last Call with Carson Daly on 18 February 2009. She covered "Knocked Up", originally recorded by Kings of Leon who had approached Lykke to cover a song of her choice, and "Gifted" in which she performs with Kanye West. Li performed at the 2009 Coachella Valley Music and Arts Festival on 19 April and the 2009 Lollapalooza festival on 8 August as part of the promotional tour for Youth Novels. A remixed version of her song "I'm Good, I'm Gone" was featured in the 2009 horror film Sorority Row. The song "Possibility" was written for the 2009 film The Twilight Saga: New Moon. Li had been asked to write a song to the film soundtrack but was reluctant to commit to the project. It was after she had seen an early screening of the film that she decided she wanted to contribute to the soundtrack. The soundtrack was released on 16 October 2009.

Background: Chrisye was born Christian Rahardi in Jakarta on 16 September 1949 to Laurens Rahadi, a Chinese-Betawi entrepreneur, and Hanna Rahadi, a Chinese-Sundanese housewife. He was the second of three sons born to the couple; his brothers were Joris and Vicky. The family lived on Talang Street near Menteng, Central Jakarta, until 1954, when they moved to Pegangsaan Street (also in Menteng). While attending GIKI Elementary School, Chrisye befriended the neighbouring Nasution family; he became especially close to Bamid Gauri, with whom he played badminton and flew kites.
Context: Chrisye's tenor voice and performance on Badai Pasti Berlalu led Amin Widjaja of Musica Studios to ask him to sign with Musica; Widjaja had been scouting him since the release of Guruh Gipsy. Chrisye agreed on condition that he be allowed creative freedom, to which Widjaja reluctantly agreed. In May 1978 Chrisye began work on his first album with Musica, Sabda Alam (Nature's Order), incorporating several songs by other artists and some written by himself, including the title song. He recorded it after locking himself in the studio with the sound engineer and arranger; despite Amin's wanting to monitor their progress, Chrisye refused to allow him access. The album, greatly influenced by Badai Pasti Berlalu and drawing on the double tracking technique pioneered by the Beatles (in which the vocals are recorded twice to achieve fuller sound), was released in August that year. Heavily promoted in a campaign during which Chrisye was interviewed on the national television station TVRI and on radio, the album eventually sold 400,000 copies. The following year Chrisye recorded Percik Pesona (Stain of Enchantment) with Jockie. Produced after Amin's death, the album featured songs written by Chrisye's close friend Junaidi Salat, as well as Jockie and Guruh. The album's title was chosen by vote; the titular song was not released as a single. Percik Pesona, released in August 1979, was a critical and commercial failure. After discussing the issue with other artists, Chrisye blamed the album's failure on its similarity to Badai Pasti Berlalu. As a result, following a period of contemplation, he began branching out into different genres. That same year he was on the panel of the Prambors Teenage Songwriting Competition, held on 5 May. After deciding that romantic pop songs influenced by easy listening would suit him best, Chrisye began recording his next album, Puspa Indah (Beautiful Flower). All but one of the songs were composed by Guruh Sukarnoputra; the album also featured the English-language "To My Friends on Legian Beach". Two of the songs, "Galih dan Ratna" ("Galih and Ratna") and "Gita Cinta" ("Love Song"), were used in the 1979 film Gita Cinta dari SMA (Love Song from High School); Chrisye played a minor part in the film's sequel, Puspa Indah Taman Hati (Beautiful Flower in the Heart's Garden), as a singer. Due in part to the popularity of the film, Puspa Indah was well received and sold well; "Galih dan Ratna" and "Gita Cinta", released as singles, were also commercially successful. In 1980 Chrisye appeared in the Indonesian film Seindah Rembulan (As Beautiful as the Moon); at first reluctant to accept the role, he was convinced by Sys NS that it would be fun. He later regretted the decision, considering the film crew unprofessional and often fighting with director Syamsul Fuad. The following year, he released Pantulan Cita (Reflection of Dreams), a collaboration with Jockie. After the album flopped, Chrisye took a long sabbatical.
Question: when did his solo career begin?
Answer:
Chrisye's tenor voice and performance on Badai Pasti Berlalu led Amin Widjaja of Musica Studios to ask him to sign with Musica;
