Jagged Edge is an American mainstream R&B group signed through Jermaine Dupri’s So So Def Recordings. The group has had a number of hit singles, many of which are produced by Dupri. The group’s members include identical twin lead singers Brandon and Brian Casey as well as Kyle Norman and Richard Wingo. In addition to writing the bulk of the group’s material, the Casey brothers have also written for Usher, Nivea and Toni Braxton.
Wingo was a late addition to the group after the departure of an original member Al, he was added after Kandi Burruss of Xscape recommended he be added. Burruss was also the one who brought the group to the attention of Dupri, who signed them to his Columbia Records distributed imprint, So So Def Recordings.
