I am attracted to her melodic sway kinda voices. Good on a record better still on the way she sang it on live. I think the way she done every of her show is quite similar to Bjork. Weird set of stage and colourful glow in the dark custom and clothes of every bandmate. Try to listen to this song. I am sure you'll love her song.
Sia Furler - Soon We'll Be Found
*try her other song which is my fav ; "Clap Your Hands" and "Buttons"
