The Interrogator is an ideal title for an album by Elizabeth Nelson’s hyper-literate band, the Paranoid Style. In her dual roles as a critic and singer-songwriter, Nelson prods and probes, putting the central tenets of rock’n’roll underneath an unforgiving spotlight. Her subjects often are artists whose tales have been told twice over, particularly on her lively X/Twitter account, where she offers tart insights on old warhorses from the Band, Van Morrison, and Prince. Her longer writing (including at Pitchfork) emphasizes her understanding of the inner workings of both songs and records, an intuition that manifests in the group she’s led alongside husband Timothy Bracy for over a decade. The Paranoid Style adhere to the gospel of three chords and overamplification; they’re true believers who don’t succumb to piety.
