It’s been four years since Miley Cyrus swung butt naked into our conscious­ness with all the eroticism of a half-cut construction worker. Post-Wrecking Ball, the 24-year-old has continued on her image-shifting mission, despite some questionable twerking and her pysch-pop Dead Petz project, wiping away lingering memories of the innocent Disney years that kick-started her career. Her sixth album supposedly marks another change of trajectory, leaving behind her recent rap fixation and drug-fuelled shenanigans with the Flaming Lips’ Wayne Coyne to return to her pop-tinged Nashville roots.
