The lab coated, chain smoking Austrian Weirdo lacquer masterers, Dr. Dub, have just cut one of the craziest looking records I've ever seen. They worked with the Slovenian Electronic project "Sonosthesia", who used crazy, proprietary mathematical equations to alter the visual appearance of the grooves by manipulating the volume and sound at very exact intervals. It's hard to explain how it works, but I'll try anyway: Silent grooves are completely straight, with no wavering. Loud, bassier, fluctuating tones cause grooves that are have a lot of back and forth movement. By precisely controlling these two things they created this:
Check out a short Dr. Dub video about the cutting here. Also check out some of their other videos. They are extremely interesting.
