At age 20, the teen prodigy of "Royals" raised the bar, marrying the massive vistas of electronic music alongside the human-scaled and handmade on her second LP, with help from co-producer Jack Antonoff. The invulnerable high-school snark broadened into a wider emotional palette – musical too, with guitars and brass lacing through synthetic beats and dub effects. At its most ambitious, it could recall art-rock godmother Kate Bush (see the single "Green Light"). But its greatest achievement was making 21st century pop feel as genuinely intimate as as it did huge. A record that should stand as a touchstone for young pop hopefuls for years to come. W.H.
