Kris Kross was an American hip-hop duo formed in 1991, consisting of two members, Chris Kelly and Chris Smith. They gained fame with their hit single "Jump," which topped the charts in 1992. Known for their unique style, they often wore their clothes backward, which became a popular trend among fans. The duo was part of the So So Def Recordings label, founded by Jermaine Dupri. Their debut album, "Totally Krossed Out," sold millions of copies and solidified their place in 1990s hip-hop. Despite their early success, they disbanded in the late 1990s but left a lasting impact on the music industry.
