“Excited for you to sit back and experience Golden Hour in a whole new, sonically revolutionized way,” Kacey Musgraves tells Apple Music. “You’re going to hear how I wanted you to hear it in my head. Every layer. Every nuance. Surrounding you.” Since emerging in 2013 as a slyly progressive lyricist, Kacey Musgraves has slipped radical ideas into traditional arrangements palatable enough for Nashville's old guard and prudently changed country music's narrative. On Golden Hour, she continues to broaden the genre's horizons by deftly incorporating unfamiliar sounds—Bee Gees-inspired disco flourish (“High Horse”), pulsating drums, and synth-pop shimmer (“Velvet Elvis”)—into songs that could still shine on country radio. Those details are taken to a whole new level in Spatial Audio with Dolby Atmos. Most endearing, perhaps, is “Oh, What a World,” her free-spirited ode to the magic of humankind that was written in the glow of an acid trip. It’s all so graceful and low-key that even the toughest country purists will find themselves swaying along.
