After having broken onto the pop music scene as a guest vocalist for the electronic act Zero 7, Sia has developed into quite the independent artist. All her music is fun and exciting, and this newest album has the most energy of any of her releases. Produced by Greg Kurstin (The Bird And The Bee, Geggy Tah), the songs contained within are a breath of fresh air. With the energy of artists like Beck (with whom she collaborated in the past) and Gnarls Barkley, her music is equally intriguing. "You've Changed" and "Clap Your Hands" are Sia's best songs since the release of "Breathe Me." "Big Girl Little Girl" has her again collaborating with Zero 7's Henry Binns, and includes backing vocals by Inara George. The album is one of the most sonically pleasing of the year, and is sure to blow up the airwaves, and trigger a plethora of remixes.
