Congratulations to Gillian Welch and David Rawlings!

@winoguy17: And the vinyl is that translucent type (I believe it is named Clarity) used by MoFi and Analogue Productions, which when placed up to a light source you can barely see through.

Clarity vinyl is a type of high-quality vinyl record that’s pressed without carbon black additives. It’s designed to improve the sound of the record.

Features of Clarity vinyl

• Clear surface: The record’s surface is clear, not black
• 45 rpm: Widens the tight curves that a cartridge has to navigate, reducing additional distortions
• Single-sided grooves: Absorbs mechanical resonances by the turntable platter
• No-pitch profile: Allows your stylus to play perpendicular to the grooves from edge to edge

From the Fremer review:

The record, plated by Gary Salstrom and pressed at Paramount (the former VMP pressing plant now at least in part owned by Rawlings) on a semi transparent vinyl formulation that may or may not be a Neotech vinyl formulation, is perfectly flat and quiet as this music demands it to be, with a textured paper gatefold jacket that's equally up to the presentational task.

@mofimadness: Ah, okay, then the Welch/Rawlings LP is not pressed using Clarity vinyl, but some other special formulation. I don't have a kitchen weight scale, but my copy of the LP is on the heavy side.
