I had the chance the other week to be involved in a live vinyl cut at the studio, and got a chance to inspect a freshly cut laquer under a microscope-- great to see these pictures along the grooves, really neat :)
Neumann lathe? Where did you do this?
Yea, Neumann lathes :) We (Metropolis Studios, London) have done it twice, once with Duke Special, and the latest with Ellie Goulding-- there's a couple of little videos on YouTube of both those events, just little promo type things, nothing that gets into the nitty-gritty too much. It's really cool to see the artist in the live room playing, and then going up to the mastering room and see the laquer being cut at the same time-- you hear the band playing on the speakers, but also you can hear the sound coming from the cutter making contact with the laquer... not a A/D process in sight! :)
