Sia Kate Isobelle Furler (born December 18, 1975), popularly known as Sia, is an Australian pop singer and songwriter. She is also part of the supergroup, LSD alongside British singer, Labrinth and American DJ, Diplo. Before her solo debut, Sia also lent vocals to British acid-jazz duo, Zero 7.

Her album 1000 Forms of Fear was released in 2014 and is her most successful album to date, with the top 10 single “Chandelier.”

After performing for nearly 15 years at nightclubs as well as releasing five studio albums, Sia took a hiatus from performing in 2010 when she began writing for other artists. Some of her most successful collaborations are “Titanium” with David Guetta, “Diamonds” with Rihanna and “Wild Ones” with Flo Rida.

Sia famously started hiding her face during her recent promotional cycles and public events. She has stated that because when she started to become a little bit famous, it felt destabilizing for her in some ways. In order for her to maintain a certain amount of privacy, she focused on writing for other artists and started covering up her face with the famous wig.

Sia has the most music videos with over a billion views on YouTube of all-female artists, with 5 videos having reached at least one billion views.

She has received a wide range of awards, including a total of 8 Grammy nominations. Sia also has had 8 of her songs go double platinum in record sales.

Despite this, her excursion into film was a far cry from her illustrious music career. In 2021, Sia would release a film entitled Music. Starring Maddie Ziegler in the title role of an autistic teen, the movie was slammed by critics and Sia fans alike for its poor representation of autism and almost ableist sentiments. Following some stormy tweets in response to criticism, Sia would delete her Twitter account. The film maintains an 8% on Rotten Tomatoes.
