The euphoric rush of Local Natives’ second album earns them a spot alongside trendsetting post-millennial rockers like Arcade Fire and Grizzly Bear: rich with melodic invention, densely orchestrated, and saturated with sweeping grandeur. Rattling percussion, thickly layered guitars, and waves of keyboards suggest a kitchen-sink approach to standout tracks like “Heavy Feet” and “Wooly Mammoth.” And yet the power in Local Natives’ songs is in the effortless melodies that are laid atop them. This deceptive simplicity—so graceful from afar, so complicated under scrutiny—is Hummingbird's magic.
