Background: Rogue Traders is an Australian electronic rock band formed in 2002 by mainstay James Ash on keyboards. In 1989, Ash met fellow original member Steve Davis, in London while both were working as DJs. Before forming Rogue Traders, the pair had worked together on many projects, including the dance music act, Union State which relocated to Melbourne in 1992. The group's name comes from the 1999 drama film, Rogue Trader.
Context: On 11 April 2002, Rogue Traders released their debut single, "Need You to Show Me", under the Vicious Grooves label, which failed to reach the top 100 on the ARIA Singles Chart. However, it did reach No. 16 on the Top 50 Club Chart. It was originally intended to be the lead single for their debut album, We Know What You're Up To, however it was cut from the album's track listing before its release. The single was recorded with Jamaica Williams providing lead vocals. Half a year later, their second single, "Give in to Me", was released on 14 October. The track had lead vocals by Melinda Richards, and was written by Ash, Davis, Josephine Armstead and Milton Middlebrook. It performed better than their first release on the ARIA Singles Chart, peaking at No. 67. At the APRA Music Awards of 2003 it was nominated for 'Most Performed Dance Work'. Ash and Richards later married and, as Melinda Appleby, she contributed songwriting credits to Rogue Traders later work.  The band's first Top 20 success came in 2003 when "One of My Kind", a remix/cover version of INXS's "Need You Tonight", was released on 23 February, which peaked at No. 10, and spent nine weeks inside the top 50. The single brought greater recognition for the band and, at ARIA Music Awards of 2003, they were nominated in two categories, "Breakthrough Artist - Single" and "Best Video" (by Sam Bennetts, Rising Sun Pictures), and won "Best Dance Release". On 5 May 2003, their debut album, We Know What You're Up To, was released, but it failed to reach the top 100 on the related Albums Chart. The third and final single from the album, "Stay?", was released on 2 June, which peaked at No. 60.  Natalie Bassingthwaighte gained popular acclaim as an actress on the Australian soap opera, Neighbours, playing the role of Izzy Hoyland from 2003. By 2004 she began working on a parallel music career creating her own demos: songs with an acoustic-rock sound when, late that year, she was recruited as the lead singer for Rogue Traders. Upon being presented with the band's music, Bassingthwaighte auditioned for Ash and Davis. The pair had auditioned 15 to 20 candidates, and after she performed their song "Voodoo Child", she became the band's front woman.
