St. Louis' finest stormed into our New York studio back in May to talk about his upcoming album, 'Brass Knuckles.' Ready to make his big comeback, Nelly admitted that it had been a while since his last album, 'Sweat/Suit,' but explained his absence. "I lost my sister in 2005 and that was like the worst thing that ever happened to me. So dealing with it took a whole...it took time."

Now, after a four-year hiatus, the rap star is finally releasing his fourth (technically his fifth, since 'Sweat' and 'Suit' were released separately, though on the same day) studio album. Buy 'Brass Knuckles' on iTunes.

Check out the video interview.
