The album’s title, exclamation point, and all come from the song “Airplane Air,” and it’s echoed in the album’s final song, “Pressure,” a song Gohl wrote for his wife and longtime partner. “Be safe,” he sings, “I will need you around.” It’s a song that sounds like nothing else in their catalog—ringing harmonics, chiming chords, vocal harmonies—but the sense of interdependence is near the center of Deeper’s music, from the way Gohl and McBride’s guitars jigsaw together and interlock with Bhatti’s drum patterns and Fairbairn’s bass to the lyrical vulnerability at the album’s core. That sense of mutuality makes this restlessly curious, stylistically broad album feel like the most coherent portrait of who Deeper is. Or, as McBride ultimately frames it, “Careful! is about looking out for one another.”
