ILLMATIC XX

Nas will head on a month-long tour for "Illmatic" in October.

Following the anniversary of Nas' seminal "Illmatic", we decide to take a look at how all his other albums stack up against it. You can probably guess what makes No. 1, but where do some of his other efforts place?

Listen to some of the music featured on Nas' "Illmatic XX" re-release.

Nas made copies of "Illmatic" for his friends, but didn't predict how widespread the leak would become.

Nas announces an upcoming "Illmatic XX" album, which will celebrate the 20th anniversary of Nas' debut album.
