My guess, circa 1987 because I recall it was after the release of the North Star LP of Arturo Delmoni's "Songs My Mother Taught Me," and we were in discussions with MFSL to make the CDs that North Star did not want to.
Herb Belkin believed that cryo was not necessary, because gold CDs were so good.
BTW, when I had a bunch of CDs cryo'ed for my own use, when I put on the Arturo Delmoni Ysaye-Kreisler-Bach solo recital, the woman I was married to at the time, who was a cellist and choral singer, recoiled and exclaimed,
"WHAT have they done to Arturo's violin?!?!? It sounds like a VIOLA being played in the fifth position!!!
That really happened!
