The answer to the question: What month did the group that had been together for a decade decide to go on hiatus? is inside the article: In June 2001, Silverchair entered a studio in Sydney with producer David Bottrill (Tool, Peter Gabriel, King Crimson) to start work on their fourth album, Diorama. Johns formally assumed the role of a co-producer. The album name means "a world within a world". Most tracks came from Johns' new-found method of writing material on a piano, a technique he developed during the band's break after Neon Ballroom.In order to complete the vision for Diorama, several other musicians contributed to the album, including Van Dyke Parks, who provided orchestral arrangements to "Tuna in the Brine", "Luv Your Life", and "Across the Night". Paul Mac (from Itch-E and Scratch-E) and Jim Moginie (from Midnight Oil) both on piano also collaborated with the band. While recording Diorama, Johns referred to himself as an artist, rather than simply being in a "rock band". Upon its release, critics commented that the album was more artistic than previous works.Early in December, the first single, "The Greatest View", was released to Australian radio networks. Its physical release in January 2002 coincided with the band's appearance on the Big Day Out tour. Early in 2002, Johns was diagnosed with reactive arthritis which made it difficult for him to play the guitar and subsequent performances supporting the album's release were cancelled. In March, Diorama was issued and topped the ARIA Albums Chart – it became their fourth number-one album and spent 50 weeks in the top 50.Five singles were released from the album: "The Greatest View", "Without You", "Luv Your Life", "Across the Night", and "After All These Years" – "The Greatest View" charted highest, reaching No. 3. In October, Silverchair were successful at the ARIA Music Awards of 2002, winning five awards including 'Best Rock Album' and 'Best Group', and 'Producer of the Year' for Johns. The band played "The Greatest View" at the ceremony: the song was also nominated for 'Best Video'. Two singles (and a related video) were nominated for further ARIA Awards in 2003.
