Sia has released her uplifting new single “Original,” off the soundtrack for the upcoming Robert Downey Jr. film Dolittle. “Original” marks Sia’s first new solo song since 2019’s “Out There,” a collaboration with Hans Zimmer that served as the theme song for the BBC’s nature documentary One Planet, Seven Worlds. Sia Kate Isobelle Furler (/ˈsiːə/ SEE-ə; born 18 December 1975) is an Australian singer, songwriter, voice actress and music video director. She started her career as a singer in the acid jazz band Crisp in the mid-1990s in Adelaide. In 1997, when Crisp disbanded, she released her debut studio album titled OnlySee in Australia. She moved to London, England, and provided lead vocals for the British duo Zero 7. In 2000, Sia released her second studio album, Healing Is Difficult, on the Columbia label the following year, and her third studio album, Colour the Small One, in 2004, but all of these struggled to connect with a mainstream audience.
