She has an amazing, breathy voice that sometimes hints of Tori Amos but can occasionally be over mannered, to the detriment of the lyrics. Ending the song on a barely audible whisper is a powerful technique, though, ensuring this remains a step above the likes of Dido.

Probably not commercial enough for heady chart success, but certainly worth investigating if you've enjoyed Sia's work with Zero 7. A fantastic voice awaits.
