A Passage In Time showcases Dead Can Dance’s work between 1987 and 1991, documenting the heady middle years of the dark, doomy ambient pioneers. The duo's obsession with mystical and sacred music from various eras and places gives their sound a timeless, almost sci-fi edge: "Cantara" pairs martial neo-folk with Middle Eastern vocal stylings, "Saltarello" is a Celtic dance with a hint of menace, and "The Writing On My Father's Hand" wafts medieval canticles through the lens of modern synth technology.
