In recent years for me:
Some Rap Songs
I loved both singles and was a huge Earl fan so I expected something special. I got one of my favorite rap albums oat
SAVAGE MODE II:
I’ve loved every Metro x 21 collab in the past. SM 1 and Without Warning are two of my favorite trap projects so I was expecting heat, but the album was even more cinematic and well-arranged than I anticipated
Whole Lotta Red:
As a huge fan of S/T, Die Lit, leaks and older SoundCloud tracks, I expected this to be great, even with the delays and drama. I didn’t expect this man to reinvent his whole damn sound and go 24 for 24 on the track list while keeping things exciting, interesting, and well-performed
Some Rap Songs is a great example
After waiting years for a follow up, We knew it was gonna be special, but I would have never guessed it would have turned out how it did

Hearing that Ye was going back to rapping & all the dope s*** he dropped during GOOD Fridays had my hype through the roof.
Once the album dropped, I couldn't believe how much dope s*** he had given us during that time span.
Oh. I misread the question. I thought OP worded it to mean rap albums you didn't expect to be impressed by that blew you away.
I'd say TPAB.
