After collaborations with Crisp and Zero 7, then two solo albums as good as relatively unknown (See Only then Healing is difficulty), it is with the disc "Colour the Small One" that Sia has definitively marked the spirits and splashed music world of his unclassifiable talent. With his songs often tinged with deep melancholy, or even a poignant sadness (Do not bring me down, Numb, or Breathe me known to be the closing song of a magnificent series ...) Sia book his audience an incredibly homogeneous and accomplished work.
