Their first hit, "Gimme What U Got", gained popularity in 1996. In 2000, the group signed with Universal Records. Their debut album, Free City, was released after Nelly's solo breakthrough, achieving Platinum status in the U.S. Members of St. Lunatics pursued solo careers, and Nelly opened a music production school. An anticipated album in 2009, City Free, was never released. City Spud served a prison term for a robbery-related crime and later performed with Nelly at the 2023 Grammy Awards.
