Sydney siblings Angus and Julia Stone found their alt-folk destiny noodling on guitars as backpacking teens. His roots-pop croak and her dark, baby-doll whimsy made a winning combination on the 2006 festival circuit. Their first album, A Book Like This, hit the ARIA Top 10, followed by a string of rustic and fragile EPs. Down the Way was a triple-Platinum No. 1 smash in '09. The Stones' divergent paths as solo artists continued to fuel a thrilling and mysterious dynamic on their self-titled third album, produced in the US by Rick Rubin in '14.
