Among the new songs is 'Getting Married,' about the Queens, New York, rapper's engagement to "Milkshake" singer Kelis. "It asks, 'How does a man who's progressing, but still holding on to his nuts, talk about getting married?'" he says.

Kelis helps out on the song, but the album is mostly solo, a throwback to Nas' early work. Disciple will be a double CD, a conceit many rappers have failed at. "A lot of double albums didn't cut it," Nas admits, "but with mine, I need that much time to say what I need to say."
