OK, so album covers that scared the crap out of me. There are many many many more. I think quite a few of them were designed by Hipgnosis. The top four were for sure
Jesus Christ, horrifying
And of course ANYTHING to do with Pink Floyd The Wall was the scariest.
Loved the Ummagumma cover because of the house of mirrors endless aspect. You know that that was probably done with exacto knives and glue. All these years later I notice how weird it is that the album in the picture is Gigi
Makes me sad that kids don't have this now because it really made my imagination run wild. I'm sure they have other things like that, but it was such a window into the adult world but in a way that was just scary enough to be fascinating. It wasn't nightmare scary like horror movies or anything.
And of course, MC Ham's aunt and uncle were responsible for some good 80s metal ones (which my dad didn't listen to) like the quiet riot mask and the Van Halen angel with the cigarette.
