You can’t get Deeper if you’re standing still. That’s intentional, says the Chicago quartet’s Nic Gohl. “Does it feel good when you’re listening to this song? Does your body want to move with it?” These are the questions he asked himself as he and bandmates Shiraz Bhatti, Drew McBride, and Kevin Fairbairn were writing and recording Careful!, their third record and Sub Pop debut. “I wanted these to be interesting songs, but in a way where a two-year-old would vibe out to it,” Gohl adds. “It’s pop music, basically.” “Build a Bridge” uses a prickly guitar line to launch into big, smeary art-pop, its emotional palette clear, well-defined, and easy to latch onto. On “Sub,” Gohl sings above and below the melody like Ian McCulloch, bellowing and wondering and ruminating and rounding into swaggering confidence that the band rises to meet. It’s festival headliner music that still feels like it was written in a garage. That fraternal interdependence is near the center of Deeper’s music. The musical and lyrical devotion to mutuality makes this restlessly curious, stylistically broad album feels like the most coherent portrait of who Deeper is. Or, as McBride ultimately frames it, “Careful! is about looking out for one another.”
