Never run out of Here Lies Love tracks. That album is an epic, which it had to be to cover the true life adventures of Imelda Marcos. David Byrne and Fatboy Slim trimmed no fat, it seems, in setting that story to music. Rounding up close to two dozen star vocalists for the project was above and beyond. This one stars Sia, who is both oddly ubiquitous and oddly anonymous. As a hired gun songwriter and guest vocalist, she’s had a hand in more blockbusting hit singles than I can count, for such mainstream collaborators as Jennifer Lopez, Pitbull, David Guetta, Rihanna and it seems like everybody else who’s been in the Top 40 lately. As an autonomous solo musical entity, she’s acclaimed but decidedly on the weird side, with a penchant for cryptic videos and equally cryptic wigs. In between those polar sides, lies a vocal powerhouse.
