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?

Not sure if all music referenced above is considered "rap"

" Rap is a type of music in which the words are not sung but are spoken in a rapid, rhythmic way."

Prefer old school myself
NWA, Snoop, Ice Cube

Thanks for all the suggestions.
I am hoping for Rap that incorporates sophisticated musical elements like Kendrick Lemar.
