Nelly rocked the microphone, the crowd, and the club Sunday night at urban lounge the Shrine during the Chicago stop of his "The Black Affair" party tour.

The Vibe magazine-sponsored trek, which coincides with the 10th anniversary of Nelly's "Country Grammar" album, comes to Home nightclub July 23, where it concludes.

Nelly, flanked by St. Lunatics Ali, Murphy Lee, Kyjuan, City Spud, singer Avery Storm and others, took over hotspot the Shrine, reminding the Chicago crowd, which was decked out in all black as requested, how it's done St. Louis-style.

After the DJ warmed up the up-close and personal crowd with hits from Justin Timberlake, Vanity 6, Janet Jackson, N.E.R.D., Parliament-Funkadelic, and The-Dream, Nelly walked out onto a VIP area above the bar, slightly earlier than scheduled, and the crowd went wild.

After rapping, ad-libbing, and shouting out over beats by Junior Mafia, Too Short, Beyonce and more, Nelly got into his own hits beginning with "Country Grammar," a song that prompted St. Lunatics' Ali to shout to the crowd "If you don't know this, just leave."

No one left.

"E.I.," "Grillz," "Shake Ya Tailfeather," "Hot in Herre," and "Tip Drill" followed, and kept the crowd pumped.

In addition to paying a bit of homage to his past with "Country Grammar," Nelly announced a release date and title for his next CD. Check out "Nelly 5.0″ on Sept. 21.

During this Father's Day event, Nelly gave several shout-outs to the day, and made special mention of his teenage daughter.

Crown Royal Black presented the evening.

"Country Grammar" was released June 27, 2000, and has sold over 9 million copies in the United States, making it one of the best-selling rap albums of all time.
