Not pulling any punches, Sia launches into Elastic Heart with what could pass as a hook in a lesser song, soaring with fearlessness on each and every syllable, artful in its majesty. Pop perfection, Sia’s powerhouse voice dynamic without ever seeming showy. I suppose I should talk about the vid with Shia LeBeouf and Maddie Ziegler? It’s great. Check it out. On the web. Cheers.
