THEN CAME THE MORNING, the second album by the Southern-born, Brooklyn-based indie-folk trio, The Lone Bellow, opens with a crest of churchly piano, a patter of drums, and a fanfare of voices harmonizing like a sunrise. It's a powerful introduction, enormous and overwhelming, as Zach Williams, Brian Elmquist, and Kanene Pipkin testify mightily to life's great struggles and joys, heralding the morning that dispels the dark night: 'Then came the morning! It was bright, like the light that you kept from your smile!' Working with producer Aaron Dressner of the National, The Lone Bellow has created a sound that mixes folk sincerity, gospel fervor, even heavy metal thunder, but the heart of the band is harmony: three voices united in a lone bellow.
