Given the question: A friend asked me to answer this question: What is the full name of the person that Chrisye refused access to?, using the article: 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..., what would be the answer ?
The answer is:
Amin Widjaja
