It would take more words than a live review should ever have to dive into how the music released by Twain and her producer ex-husband Mutt Lange — the sonic architect behind AC/DC’s “Highway to Hell” and “Back in Black” and Def Leppard’s “Pyromania” and “Hysteria” chart-topping records — did more to make country palatable to broader, pop audiences (and turn pop-country into the cultural presence it is today). Twain’s 100-minute set, comprised largely of material from her late 1990s commercial heyday, leaned into that legacy and served as a well-earned victory lap for the pop-country icon.
