What Rap available on vinyl sounds great on a good system?


This is my central question about Rap. In my recent exposure I have discovered one album that is undeniably Rap and is fascinating, musically complex and acoustically challenging. Kendrick Lemar’s To Pimp a Butterfly.
I bought the CD and am enjoying listening. I am a fan of Modern Classical and this album is unique in its structure but enfolds in a Modern Classical Avant-garde manner. Interesting and engaging.
What are some other Rap LPs that have this kind of complexity?

Definitely De La Soul's "Anonymous Nobody" is impeccably produced.
Also, try a Dominique Fils-Aime LP or CD - not rap, but good pseudo-hiphop

Sir-Mix-A-Lot 

Chief Boot Knocka 
Thundercat, unbelievable 
Waiting for millercarbon to chime in with his favorite Rap on vinyl.....
