Experimental musician Whitney Johnson has, over the course of her previous two albums as Matchess, considered the sound of sight from different points of view. 2013's Seraphastra searched for the other side of the visible, 2015's Somnaphoria filtered that sight thru dream vision. Sacracorpa completes the trilogy, and grapples with the hidden inner realities only ever uncovered during a crisis. Johnson's extraterrestrial soundscapes pulse and writhe, at times sounding like funeral hymns or spiritual invocations, summoning forth the circuit-fried ghosts in the machine that dwell just beyond.
