The Autobiography by Vic Mensa just came out and I'm really pleasantly surprised with it. It makes me really emotional esp.
this song
I think it's all true stuff (hence the name) which makes it that much more touching
Also Tyler the Creator focuses a lot on lyrics and telling a story and while I personally don't like the newest albums (Cherry Bomb, Flower Boy) I really like
Wolf and Bastard.
Childish Gambino's Because the Internet is another good album and I think it's supposedly really deep and has an entire script and stuff but I never really got into that.
This is actually the song that first got me into rap. I've probably listened to this song well over 200 times.
I've been listening to a lot of Joey Bada$$ recently and I think he and his group Pro Era are all really talented. Try listening to his most recent album All American Bada$$. it slaps
MF DOOM is a little bit more old style rap but I think he was one of the first people to take rap to a new level of storytelling and I know Tyler the Creator was influenced by his work.
Here's my favorite album by him:

Atmosphere,
Brother Ali, and
Aesop Rock If I remember correctly, Aesop Rock has the biggest vocab variety of any rapper.
