An erudite catalogue of some of the most peculiar records ever made. We have lined up, described and put into context 500 "albums" in the expectation that those of you who can't help yourselves when it comes to finding and collecting music will benefit from these efforts in two ways. Firstly, you'll know you are not alone. Secondly, we hope that some of the work covering the following pages leads you to new discoveries, and makes your life slightly better as a result.
