The union of composers Lawrence English and loscil aka Scott Morgan is seamless, sublime, and long overdue. Born of a conversation centered on the notion of “rich sources” as a forge for electronic music, Colours Of Air is a collection of recordings of a century old pipe organ housed at the historic Old Museum in Brisbane, Australia, which were then processed, transformed, and elevated into eight majestic electro-acoustic threshold devotionals. The timbre of the instrument and spatial fluctuations of room tone infuse the music with a subdued, sacred feel, like vaulted light in a nave of stained-glass.

They describe the album as “an iterative project, a reduction and eventual expansion,” sifting the swells and drones of the organ for every shivering shade of radiance. The tracks are named for the hue each piece suggests—from the gauzy levitational miasma of “Yellow” to the pulsing melancholic mirage of “Violet” to the seething twilit sandstorm of “Magenta.” Morgan and English are both adept at conjuring moods of muted grandeur, like landscapes veiled in dusk, still looming and luminous. Here their combined powers open pathways to heightened realms of deep listening and bewitching restraint, finding flickering infinities in ancient configurations of wind, brass, stone, and dust.
