A landmark of acoustic pop and intelligent, searching spirituality, Jars of Clay’s debut presaged folk music’s renaissance and generated 10 classic songs of faith, doubt, and devotion. The pounding sing-along “Flood” was the big hit, but “Liquid,” with its samples of monastic chanting, was sly in its inventions. “Love Song for a Savior” raised the bar for passionate, personal expressions of worship; “Like a Child” and “Boy On a String” still resonate with their intelligent craft; and “Worlds Apart” remains gripping in its benedictory fervor.
