How can I find an album no one knows exists?

I'm asking not just if you've heard of it, but how to find some random album in general. See, the band Dead Confederate released an album called "The Cover Story", but the only trace of it's existence is on this article on wikipedia: a href="http://en.wikipedia.org/wiki/Polly_(song)" rel="nofollow"http://en.wikipedia.org/wiki/Polly_(song…/a in the section about covers. That's the only place that I've even heard of it. I even got to meet a couple of guys from the band, but forgot to ask this. Any websites where I can find this, or others?
