Listen To Sia’s “Bird Set Free”

Sia's next album, This Is Acting, is entirely composed of songs she wrote for other people. She loves easily graspable metaphors along the lines of "shine bright like a diamond;" her new track revolves around the image of "a bird set free." Drums land like rifle shots, and piano keeps a steady rolling momentum.

This Is Acting is scheduled for release on 1/29. Read about how the singer's disappearing act is changing the landscape for women in pop.
