Query: A genre-changing album

With 192 reviews so far I'm not sure I'll sway the ratings much, but when this album came out, way back in 1989, it truly transformed rap. No album before it came anywhere close to the density and variety of sampling used on Paul's Boutique. The recurring theme of resurrection, unbelievable rhymes and cultural references (some pop, some not) and an unbelievable tapestry woven out of nearly every song that had ever come before it. Definitely on my short list for best album of all time.
