Please answer the following question: The answer to the question: What is the full name of the person that wrote most of the songs for Diorama? is inside the article: Diorama is the fourth studio album by Australian alternative rock band Silverchair, released on 31 March 2002 by Atlantic/Eleven. It won the 2002 ARIA Music Award for Best Group and Best Rock Album. The album was co-produced by Daniel Johns and David Bottrill. While Bottrill had worked on albums for a variety of other bands, Diorama marked the first production credit for lead singer Johns. Johns wrote most of the album at the piano instead of his usual guitar, while the band took a 12-month break following their previous studio album, Neon Ballroom. Silverchair worked with composer Van Dyke Parks on Diorama; the album contains numerous orchestral arrangements and power ballads, a change from the post-grunge music typical of their earlier work, but consistent with the band's previous orchestrations on Neon Ballroom. The album's title refers to "a world within a world". Five singles were released: "The Greatest View", "Without You", "Luv Your Life", "Across the Night" and "After All These Years". All except "After All These Years", a promotional single, appeared on the Australian singles chart. Diorama was successful in the charts but was not as well received by critics as the band's earlier albums. It reached number one on the Australian Recording Industry Association (ARIA) Albums Chart and received a rating of 71 (out of 100) on review aggregator Metacritic. It was certified triple-platinum by ARIA, selling in excess of 210,000 copies, and won five ARIA Awards in 2002. Diorama was nominated for Highest Selling Album in 2003, and three songs from the album were nominated for awards over the two years., can you guess it ?
