“Pro Anti Anti” is the latest of Liars’ art-centric music videos. Previously, they’ve used the open source #RGBDToolkit for “The Exact Color of Doubt” and artist Ian Cheng’s visuals for “Brats.” This time, director Yoonha Park created realistic, layered wax casts of Angus Andrew and Aaron Hemphill’s faces using 3D-scanning software and various mechanized and manual processes. It all builds up to the final money shot of their faces melting, popping, peeling and dribbling in iridescent rainbow hues all over their pedestals. It’s actually not so much a music video but a “how it’s made” style video of all this art-making. Apparently, it’s called “manufacturing porn” and there’s a whole culture around it.
