Folk rockers Buffalo Traffic Jam found breakout success with “Fool’s Gold,” a raw account of youthful ambivalence that calls back to the wildly popular roots-pop era of the mid-aughts/early 2010s, led by bands like Mumford & Sons and The Lumineers. The Montana-based duo composed of Frankie Cassidy and Nathan Ross takes the same earnest, warm approach as those forebears, but where those acts leaned into the fragile optimism of that earlier era, Buffalo Traffic Jam sound of a piece with the current moment with their plainspoken meditations on grief and change. Produced by a team that includes Noah Kahan collaborator Carrie K, Pictures of You takes a less-is-more approach to arrangement, sticking largely to acoustic instrumentation and incorporating elements like percussion at moments of emotional crescendo. Songs like “Fool’s Gold” and opener “Hanging on Hope” take their time building to cathartic release, like when, on the latter, a silent, pregnant pause after the second verse gives way to a stomping chorus. Cassidy and Ross are at their best on standout “How to Breathe,” a rollicking anthem about the one that got away.
