Perhaps soon I will write an editorial on albums that are not truly concept albums (or maybe they are), but there are some common nouns. Let it be clear, there is always a trait that unites them, but usually it’s about ear rather than writing; it depends.
But think about it, when the thread is both woven and electrifying (and you realize it after repeated listens because it’s said 5 times and then declined into abstract concepts...) it’s another thing.
