Reading Time: 5 minutesLiberty Grove, established in 1835, is the type of church typically associated with Sacred Harp. The church interior is unadorned. Bare pine walls. Plain metal fans and naked bulbs dotting the pine ceiling. Worshippers scattered among straight pine pews in uneven clusters, their hands rising and falling in 4/4 rhythm, down on the first beat, up on the third. Feet keep time as well.
