"Kidung Abadi" (Indonesian for "Eternal Ballad") is a song written by father and daughter team Erwin and Gita Gutawa for the Kidung Abadi Chrisye concert; the concert was held on 5 April 2012 to commemorate the fifth anniversary of Chrisye's death. The song was created over a period of three months by splicing syllables from previously recorded vocals by Chrisye. At the concert, spliced black-and-white footage of Chrisye was shown lip synching to the song while Erwin's orchestra performed the music. The song was well received: the audience gave it a rowdy ovation, while critics praised its lyrics and described it as one of the best parts of the concert.
