Benjamin David Gillies is an Australian musician, best known as the drummer of Australian rock band Silverchair from 1992 until the band went on hiatus in 2011. In 2003, Gillies formed Tambalane with Wes Carr, initially as a songwriting project; they released a self-titled album in 2005 and toured Australia but subsequently folded. By June 2011, after Silverchair's disbandment, Gillies was in the final stages of about 12 months of working on his solo album, and he said that it was not a continuation of his earlier work with Tambalane. In 2012, he formed Bento, in which he performs lead vocals, and released the band's debut album Diamond Days.

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.
