Sia is a pop music veteran who’s been making music for decades, building a fanbase loyal to her sound and special image, making something of an industry statement by performing and appearing with her face fully covered. She’s also directed many of her own music videos, generating cinematic experiences for her work, receiving acclaim for her collaborations with dancer Maddie Ziegler. Sia steps up to feature-length helming with “Music,” reuniting with Ziegler for a drama about love and redemption, with the songstress hoping to blend flashy musical numbers with a serious understanding of human interaction and motivation. “Music” has flashes of style and energy, but those moments remain with song and dance, playing to Sia’s strengths while the rest of the picture wrestles with tone and even basic editing, hinting that someone, somewhere lost their nerve with the original conception of the endeavor (which was shot nearly four years ago). There’s passion for the project, which is refreshing, but for her big screen debut, Sia’s storytelling focus is out of whack. Read the rest at Blu-ray.com
