Jagged Edge formed in Atlanta, Georgia. The group is comprised of identical twins Brandon and Brian Casey, Kyle Norman and Richard Wingo, who was added by recommendation of Kandi Burruss of Xscape. Kandi took the group's demo to Jermaine Dupri who signed them to his So So Def label.
In 1998, the group released their first album, A Jagged Era. The album managed to go gold and featured the single 'Gotta Be.' The track reached #11 on the R&B charts and #23 on the Hot 100.
Following up their debut album, Jagged Edge released J.E. Heartbreak in 2000. The album was the group's breakthrough with several popular singles. The album went double platinum and had the hit single 'Let's Get Married' which topped the R&B charts and reached #11 on the Hot 100. The album's second single, 'He Can't Love You' had similar success, reaching #3 on the R&B charts and #15 on the Hot 100. It also featured the track 'Promise' which, albeit a late single coming out in 2001, reached #1 on the R&B charts and #9 on the Hot 100.
The group's third release, Jagged Little Thrill, was released in 2001 and went platinum. It's success was in large part, due to the up-tempo 'Where The Party At,' which reached #1 on the R&B charts and #3 on the Hot 100, the group's highest charting single.
Hard, Jagged Edge's fourth album, was released in 2003 and went gold. The album's single 'Walked Outta Heaven' performed well on the charts, reaching #6 on the Hot 100 and #2 on the R&B charts. During the same year, Dupri and So So Def left for Arista Records but Jagged Edge stayed with Columbia.
In 2006, the group released their last album to date, the self titled Jagged Edge.
