I interviewed Sia, and you can read the piece over at Idolator.A FEW HIGHLIGHTS:
On writing songs for Christina Aguilera: "There are four of them... Then we did another one for her movie with Cher. So it’s been a really good collaboration, actually. We really got along great. We didn’t bin anything, which was good."
On contributing to David Byrne & Fatboy Slim's Here Lies Love: "The Santigold track is so amazing. And the Roisin Murphy track is so amazing... It was like David just emailed me and asked me if I wanted to sing on a track. I was like, um, hi—you’re David Byrne. Yes, yes, yes. The answer is always yes!"
On doing her new album with Greg Kurstin: "Greg produced the whole album. It was my usual band, and then Greg played the piano and Nick Valensi from The Strokes played the guitar. We had scheduled four weeks for it but it took two-and-a-half, so that was awesome. It just came barfing out. Then Greg took it away."
