I have the Prince Of Darkness box set which features most of this album as well.
I was listening to a couple of albums from 1967 and remembered this one. The music is not really that exciting in today's world, but I like it for its different lyrics which imo don't match the style of music. That is what makes it interesting for me. It has grown on me over the years.I had a listen to this yesterday as well. I still have not found it very interesting but I’ll not give up on it yet.
