The other day out of some masochistic impulse I put on a album I did in 2000 and much to my shock the disk began to skip. I checked for scratches and dirt but the disk was clean.
I put on someone else's work and no errors appeared. I replaced it with one from my label from 2001 and that one also skipped. I began to panic and quickly grabbed one from 2006 and it played fine, the same went for one from 1998.
With two disks, isolated. I sort of wondered whether the machine I was playing them in had become picky. Although not a technical nor logical explanation it does happen.
Let's step back for a moment. Since 1998 almost all music on my label has been sold online and in person as a packaged & burned CD-R. Although there have been a few releases where traditional manufacturing was done due to a slightly larger demand, the general rule is that my audience is small and technology finally got to a point where I didn't need to store slow moving product.
In that time I have never received complaints of quality nor failure, although when I first started to do product as a made to order thing more then a few folks thought I was nuts.
