Sia gained fame initially through songwriting and providing vocals for other popular artists. She became even more popular through the release of her single "Chandelier". Sia is known for maintaining a consistent brand image across her albums, music videos, and performances through similar concepts and themes of light versus dark, the use of child dancers like Maddie Ziegler to portray herself, and her iconic wig. She uses these consistent elements of her image and videos to focus attention on her music and ideas rather than herself as the artist.
