is a bit of a sly nod to a public who watched explore a defiantly loud post-adolescence: she may be older, but she's not necessarily grown up. The joke is, is most certainly an album that announces 's mature phase, a record that shakes off the druggy haze of -- an album cut at the height of her infatuation with -- yet retains the services of , a producer/songwriter who collaborated with her on that 2015 digital-only effort. That's the first sign that may not be the back-to-the-roots move its retro-iconography and duet may suggest. Certainly, there are country-ish songs scattered throughout the album -- a hoedown and a waltz, but mostly ballads -- but they're delivered with an arched eyebrow, a distancing effect accentuated by how the album unfurls with a pair of songs where brightens up the Californian melancholy of . Despite a showstopping performance or two, the kind of pyrotechnics that sound ripped from the heart, sadness isn't 's thing.

She may not bother with EDM drops or murmured vocals -- she's justifiably proud of flaunting her voice -- but she perceives no line dividing the past and the present, eagerly dressing up old-fashioned forms in newfangled sounds. If seems slightly scattered as it flits from song to song, it nevertheless adds up to a portrait of a pop star so confident of her swagger, she doesn't bother with such niceties as old-fashioned flow. She knows she's got style for miles and miles, enough to keep her afloat when the time comes that she delivers her country tunes with acoustic guitars, not digital instruments, and she has the wisdom to know that snappy sheen is precisely what this particular album needs. ~ Stephen Thomas Erlewine
