“I never thought I would see this at Newport,” singer-songwriter Lizzie No announced before launching into a scorching version of her own “Deep Well Song.” “I play a lot of folk festivals, and normally it’s like one or two Black people. Maybe that’s an accident, but more likely it’s because we’re extremely dangerous when we’re all together.” The Black Opry Revue was a joyful corrective as well as a varied display of the collective’s disparate stylings and songwriting prowess, from the fingerpicking of Buffalo Nichols to the acoustic blues of Chris Pierce to the sensitive storytelling of Leon Timbo to the beautiful balladry of Julia Cannon to the Nashville radio fodder of the Kentucky Gentlemen to the uplifting testimony of Autumn Nicholas, before culminating in a two-song delivery from festival returnee Joy Oladokun. As Lizzie No put it herself: “The Black Opry is coming for everything.”
