I found and Bought A few A&M cutout Lps myself back in the 80s I saw Herb Alpert's Beyond constantly going for 99 cents New and sealed and multiple copies same with A few Burt Bacharach titles and i even bought a couple of Lani Hall titles in the cutout bins thankfully a few Rare A&M titles Escaped "the Buyback and Destroy and Recycle" syndrome of the time.Back in the mid 70's, I contacted a business called Discontinued Records. I was looking for Crystal Illusions and Warm. Both had disappeared from the A&M listings and my copies were needing replacement. DR had them but wanted nearly $30 for each on them. They had a copy of CI with some jacket damage for $15 and I bought that copy. Eventually, used record stores started showing up in my area and they had copies of both at far more reasonable prices. I have bought extra copies of each on LP and have the CD's of each as well.
I had found Warm as a cutout and purchased it but never saw it again as a cut out.
I remember that talk of recycled vinyl but never heard of it's actual use but I guess it did.
In the cut out bins, I saw lots of releases that were not that old. By 1973 most all of the solos by Diana Ross were already in the discount bins and there was three or four of them all at once.
