You're right, the wall can get you down. It's quite hypnotic.
The song "suite sister mary" blows me away on Operation Mindcrime. For a long while it was my favourite song ever. I'm a big fan of vocalists doing changes in a song. Geoff makes it sound like there's multiple singers (4:51 - "Mary my lady of pain, always alone...") Wow, just wow.
I suppose Mindcrime doesn't get me down cause it's got riffs and well Tate, what a singer, maybe better than Halford in the 80's, he's considered a 2nd rate Halford I hear.
You maybe did not seem to like Paradise Lost's most current record, perhaps one of their classics could change your mind, one of my fav bands for sure:
