A pop star who defies labels, including that of "pop star," the ever-enigmatic Furler rose to international stardom in spite of herself, and on the back of some great tracks. The songwriter is so prodigious that, this winter, she released her seventh studio album, This Is Acting, a collection of singles this winter that she had penned for other artists who didn't record them.
