William Basinski’s On Time Out of Time is an ultra high-concept suite of avant-garde, ambient recordings with an intense visceral impact. Among the gorgeous washes of synths, brilliant textures, and lush threads of melody is something out of our earthly conception of the ordinary: source recordings from the interferometers of CalTech’s LIGO (Laser Interferometer Gravitational-Wave Observatory). Basically, you’re listening to the sounds of two massive 1.3-billion-years-old black holes merging. It’s pretty heavenly (pun intended). A shimmering, lovely piece of celestial sound art that truly is awe-inspiring.
