And it's not just music. Williams is also venturing into acting and although he can't reveal too much about the roles he has taken on, he can say that one is for a major ABC television drama and the other is a feature film expected to be shot in September.
"They saw the video for Dark Child and, funnily enough, both jobs are similar plots," he says.
The video for the album's lead single is a dark and unsettling watch, in which Williams plays a series of characters, including one that dissolves into a dribbling fit of rage mid-arrest in the back of a police car.
It's a compelling performance by the talented Williams, not to mention a cracking tune.
So it's no wonder his upcoming return to New Zealand will be a fleeting visit for a handful of shows, before he heads off yet again, this time with North America in his sights.
It is almost guaranteed the young troubadour will put Kiwi-grown alt-country firmly on the map - as he's done in Australia.
