What are your personal one-album wonders?

Are there any albums in your collection that you absolutely love even if you have no interest in the rest of the artist's discography?

First example for me, which I'm sure many can agree with, is Silent Alarm by Bloc Party. I've been listening to it since it came out and have grown more appreciative of it as years have passed (before I used to think it was too front loaded). However, besides a couple of singles here and there, the rest of their music does nothing for me.

Next one might be a bit more controversial but I don't think anything PJ Harvey has done before or after To Bring You My Love can match it. I've listened to, and at times owned, most of her discography, and while I can appreciate it, there's nothing that really keeps me going back the way TBYML does. I especially hate the production on Rid of Me.

So how about you guys? Are there any artists that you feel peaked at one album and could never match the greatness of it again?
