Greg Kurstin : (2) " Sia is like no one else I’ve ever worked with. She comes completely from this non-logical but very emotional place. I could be wrong, but she doesn’t really seem to analyse what she’s writing. She doesn’t really revise it, but goes with that first thing that comes out. " - Greg Kurstin " I left my band on my own, and it took me a long time to find major success again – almost a decade. And everything that didn’t happen during that time just motivated me to do better. " - Greg Kurstin
