One of the greatest freestyles in hip-hop history took place at, of all places, a Patti LaBelle concert. The Notorious B.I.G. and Tupac Shakur came onstage together in New York for a legendary performance. DJ Mister Cee tells the story as if it were yesterday. "That was live at Madison Square Garden," Cee said in Brooklyn, minutes from where Biggie grew up in Bedford-Stuyvesant. "It was a concert me and [Big Daddy] Kane did for the Budweiser Superfest back in 1993 at Madison Square Garden. We were the only rap group on the show. I think Patti LaBelle was on the show, Tony! Toni! Toné!. We only had 10 minutes. Being it's New York, we wanted to do something extra crazy for our show. So we asked Big to come out. Kane told me to reach out to Big.
