Apparently Angus and Julia Stone didn't know who Rick Rubin was when he emailed saying he'd be keen to produce their next album.
And Rubin didn't know the Australian siblings weren't on the best terms at the time (they'd broken up in 2011), so it says something about his approach that Julia took time to look Rubin up, and then emailed Angus suggesting it could be a good idea.
After a couple of years apart, and time to experiment with solo projects, the pair were ready to work together again - on the condition they were as open and honest as possible, something which hadn't happened in the past - and ready to work with a producer.
The result, their third album, is their strongest, loveliest collection of bluesy folk pop yet, one which embraces the dark and light side of all kinds of relationships.
There's more abandon, and more shadows in tracks like A Heartbreak, and Heart Beats Slow; there's a quiet honesty to Wherever You Are; and Angus' delivery on Get Home pricks you with loneliness.
