One of my favourites; although it's dark and twisted and a little depressing, so I don't listen to it often. It's also noisy and experimental and shouty, so I'd say it's not everyone's cup of tea. However I'd argue that it's one of the most important albums of the 90s, considering it's credited with the birth of the Post-Rock genre.
I discovered it in a backwards sort of way, after getting into bands like Godspeed You! Black Emporer, Mogwai, and Sigur Rós in college. It also eventually opened the door to hardcore and post-hardcore punk for me, which I came very late to (almost in my 30s, in the late 2010s).
Once I listened to it a few times I could see how influential it was. In fact it's still influencing bands today, like "the world's second-best Slint tribute act", Black Country New Road. I hope the lead singers of both Slint and BCNR got the help they needed.
