On her follow-up to 2010′s We Are Born, which debuted at No. 2 in her home country of Australia, Sia teams up again with producer Greg Kurstin and Strokes guitarist Nick Valensi. Other guests she recruited this time around include The Weeknd, Diplo, and Lana Del Rey collaborator Justin Parker ("Ride," "Videogames").

After releasing We Are Born, Sia retreated from the spotlight, focusing her time on writing songs for others. Her writing credits include Rihanna's "Diamonds", Beyonc�'s "Pretty Hurts" and Flo Rida's "Wild Ones", among others. You can see how those experience benefitted her own writing on tracks like the addictive lead single "Chandelier", "Eye of the Needle", and "Big Girls Cry".

Still, Sia hasn't warmed up to be famous. In an interview with DAZED, she talks about how the blonde bob in the album's artwork and worn by 11-year-old "Dance Moms" star Maddie Ziegler in the "Chandelier" video is, for her, a layer of protection from the outside world.
