Following the event, she moved to London, England and provided lead vocals for British duo Zero 7.
In 2000, Sia signed to Sony Music's sub-label Dance Pool and released her second studio album, Healing Is Difficult, the following year. Displeased with the promotion of the record, she signed to Go! Beat and released her third studio album, Colour the Small One, in 2004. Dissatisfied with the project's struggling to connect with a mainstream audience, Sia relocated to New York City in 2005 and began touring across the United States. Sia released her fourth and fifth studio releases, Some People Have Real Problems and We Are Born, in 2008 and 2010, respectively. In 2014, Sia released her sixth studio album, 1000 Forms of Fear, which was preceded by the top-ten single "Chandelier". On 29 January 2016, she released her seventh studio album This Is Acting.
Sia's music incorporates hip hop, funk and soul as a base for her vocal styling. In 2014, she was ranked the 97th richest Australian person under the age of 40 by BRW magazine, with a reported net worth of AU$20 million. Her music has received an array of accolades, including ARIA Awards and MTV Music Awards.
