For those who are unfamiliar with Aussie singer-songwriter Sia and her music, she’s the type of artist that dig deeps and delivers emotional, soul-searching, introspective lyrics over subdued electronic beats and melodies. Listening to her music, you’d think that during a live show she’d be the Fiona Apple-type of performer that is so self-absorbed and emotionally fragile, she could possibly break down on stage. That is so not the case and quite the opposite.
