Amazing close up shots of the grooves of a record, taken by Chris Supranowitz , a researcher at The Institute Of Optics at the University of Rochester. That's Rochester in New York state. As opposed to the town in Kent.
This shot is from above - the black here is the uncut vinyl.

You can see the dust particles in the shot below.

If you've got some old red/blue 3D spex you can get cosmic and check out the depth in the shot of the groove below!
