What is the difference in a 2 eye and 6 eye record

If you want to get really fancy you can look for six-eye monos and six-eye stereos. red label with black eyes on the monos, inverted on the stereos. I'll second Narrod that the two-eyes are hit and miss and the later no-eyes and everything else are very hit and miss from a quality perspective. Its unfortunate too, because Columbia's recording facilities delivered some really great sounding records - Kind of Blue, Time Out, etc.

The Kind of Blue is red label, black eye stereo Cs 8163. I have several six eye grey labels, but don't remember now if they are stereo or mono or both.

What the heck are you people talking about?

The grey label is Columbia "Masterworks" used to issue Classical,Soundtracks and Original Cast.It was issued in most if not all permutations of the artwork.From the original solid through 6 eye/2 eye/red and various later labels.Mono and Stereo.

Honest1...Columbia produced vinyl lps that had labels with what is called 2 eye or six eye motifs in the 50's and 60's.

The grey label ones seem to all be MasterWorks albums.
