I was just going to mention Attila. Though it's frequently written of as one of the worst albums ever released, I suspect most people who say that have never really listened to it and are just judging it by how radically different it is from his later work. Holy Moses is an excellent example of the distorted organ sound OP may be looking for, while Tear This Castle Down should really be regarded as a prog rock classic.

Dead Man Working by Album

Not a recommendation, but once in 2006 I was in a record store with a friend, who was taking a long time thoroughly perusing the used DVD section, and the store was playing (what I later learned was) Arctic Monkey's first album in full. I'd never heard of them, and when we walked in "I Bet That You Look Good on the Dancefloor" was playing. I thought, what is this awful, trashy punk noise??

But as the album went on, each song got better and better, and by the time "Red Light Indicates Doors are Secured" came on, I had to go up to the counter to find out who it was and what aisle I could find the CD in. Been a massive fan ever since. All except "Dancefloor."

I assume that's what it is. I believe it's called a cenotaph, but possibly that word is only used for more significant monuments than this.

I appreciate the effort, but I could appreciate it more if I knew what the original signs said.
