When was last time 1 Producer Produced an Entire LP?

Maybe I'm getting old but back when one producer produced an entire LP the record had a "Sound" to it that I personally miss. Back with Tribe (Q-Tip), Wu Tang (RZA), Gangstarr (Premo), Mobb Deep (Havoc)
Chronic & Doggystyle on up to the late 90's and early 2000's with Dilla Sound, Kanye Albums, hell even the 2 Little Brother LP's (w/9th Wonder)the artist LP's had focus and didnt sound like mixtapes. I personally like that style (of course Pete Rock & Cl Smooth joints) much better. So...

1. When was the last artist or group to use this format?
2. When was the last LP produced in this manner?
3. Do you prefer that style or the way LP's are made now?
4. Are there any combinations of artist and 1 Producers that you would like to hear?
5. ...Random comment

me:

1. I think Blu & Exile "Below the Heavens" is the last one I remember or really like
2. No sure when the last LP made in this style was released
3. I prefer one producer as I stated above.
4. Nas and Premo ....
5. RZA created the entire Wu Tang sound and at times people overlook him as one of the top 5 producers (well, I think he is)..

peace
