Sia Kate Isobelle Furler (/ˈsiːə/ SEE-ə; born 18 December 1975) is an Australian singer and songwriter. Born and raised in Adelaide, she started her career as a singer in the acid jazz band Crisp in the mid-1990s. When Crisp disbanded in 1997, she released her debut studio album, OnlySee, in Australia. She moved to London and provided vocals for the British duo Zero 7. Sia released her second studio album, Healing Is Difficult, in 2001, and her third, Colour the Small One, in 2004. Sia moved to New York City in 2005 and toured the United States. Her fourth and fifth studio albums, Some People Have Real Problems and We Are Born, were released in 2008 and 2010 respectively, and both were certified gold by the Australian Recording Industry Association and attracted wider notice than her earlier albums. Uncomfortable with her growing fame, Sia took a hiatus from performing and focused on songwriting for other artists, producing successful collaborations 'Titanium' (with David Guetta), 'Diamonds' (with Rihanna) and 'Wild Ones' (with Flo Rida).
