So decreed Queen B in a rare lengthy Instagram post about “Cowboy Carter,” which is “Act II” in her “Renaissance” trilogy that began with the underground house beats of her 2022 album that had us buzzing and bopping to “Break My Soul,” “Cuff It” and “Alien Superstar.”And while it may seem like a hair-whipping flip to take it from the ballroom to the barnyard on her latest, it is not as radical of a departure as it may seem for Bey herself, who hails from Houston, Texas, and is as Southern as any hummingbird could be.“They used to say I spoke ‘too country’/And the rejection came, said I wasn’t ‘country ’nough’/Said I wouldn’t saddle up/But if that ain’t country, tell me, what is?” she sings with a snarl in her twang on “Ameriican Requiem,” the autobiographical manifesto that opens the album.This is Bey unplugged, raw and rootsy, two-stepping across the color lines that took “Texas Hold ’Em” — the banjo-picking bluegrass stomper that previewed “Cowboy Carter” last month — all the way to No.
