Analog Vinyl Sampling from Ishac Bertran on Vimeo.

christian marclay used to do something similar in the 80s, where he would cut the vinyl then somehow glue them back togehter. this uses lasers of course, and while the effect is not as smooth as marclay's, the look very cool as objects unto themselves.

original video found on itsnicethat

and one of Marclays's Recycled Records from 1983
