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.

In July 2005 Chrisye was admitted to Pondok Indah Hospital, complaining of breathing difficulties. After 13 days of treatment he was moved to the Mount Elizabeth Hospital in Singapore, where he was diagnosed with lung cancer. Although concerned about losing his hair, which he considered part of his image, he underwent the first of six rounds of chemotherapy on 2 August 2005.  Chrisye's health improved in 2006 and in May and November he undertook long interview sessions with his biographer Alberthiene Endah. He also released two compilation albums, Chrisye by Request and Chrisye Duets; however, he reportedly did not feel well enough to release new songs. By February 2007 his health was again in decline.  Chrisye died on 30 March 2007 at his home in Cipete, South Jakarta. He was buried in Jeruk Purut Public Cemetery, South Jakarta. His funeral was attended by hundreds, including Indonesian celebrities such as his collaborator Erwin Gutawa and singers Titiek Puspa, Ahmad Albar, Sophia Latjuba, and Ikang Fawzi.  One hundred days after Chrisye's death Musica released two compilation albums. Entitled Chrisye in Memoriam - Greatest Hits and Chrisye in Memoriam - Everlasting Hits, they contained fourteen hits from albums ranging from Sabda Alam to Senyawa. On 1 August 2008 Chrisye's last single "Lirih" ("Gentle Voice"), written by Aryono Huboyo Djati, was released. The song's existence had been kept secret, and the recording date is unknown; Djati has said that it was recorded "for fun". A music video directed by Vicky Sianipar and featuring Ariel Peterpan, Giring from Nidji, and Chrisye's widow was released later.
