Like its title suggests, Dragon New Warm Mountain I Believe in You continues Big Thief’s shift away from their tense, early music toward something folkier and more cosmically inviting. They’ve always had an interest in Americana, but their touchpoints are warmer now: A sweetly sawing fiddle (“Spud Infinity”), a front-porch lullaby (“Dried Roses”), the wonder of a walk in the woods (“Promise Is a Pendulum”) or comfort of a kitchen where the radio’s on and food sizzles in the pan (“Red Moon”). Adrianne Lenker’s voice still conveys a natural reticence—she doesn’t want to believe it’s all as beautiful as it is—but she’s also too earnest to deny beauty when she sees it.
