Jagged Edge is an American R&B group from Atlanta, Georgia. The group, initially signed to record producer Jermaine Dupri's So So Def Recordings, is best known for their string of hit singles including "Let's Get Married" and "Where the Party At" (featuring Nelly), most of which were produced by Dupri. The group's members include identical twin lead singers Brian and Brandon Casey as well as Richard Wingo and Kyle Norman. The group's debut album, A Jagged Era (1997), performed modestly at the time of its release but achieved gold status; however, their subsequent albums until 2007 all became commercial successes—debuting within the top 10 of the Billboard 200.

Wingo was a late addition to the group, added after a recommendation from Kandi Burruss of Xscape. 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. The name Jagged Edge is derived from the lyrics of the beginning of RZA's verse on the song "Snakes" on rapper Ol' Dirty Bastard's debut album Return to the 36 Chambers: The Dirty Version: "Jagged Edge, Rockhead God, hard as Stonehenge..."

Jagged Edge began their mainstream recording career with the single "The Way That You Talk". They followed this in 1997 with the album, A Jagged Era which went gold, featuring the singles "I Gotta Be" and "The Way That You Talk". "I Gotta Be" which was written by the twins, reached number 11 on the R&B charts and number 23 on the Hot 100.

Following up on their debut album, Jagged Edge released J.E. Heartbreak in 1999. The album was the group's breakthrough album 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 number 11 on the Hot 100. The album's second single, "He Can't Love U" (released September 28, 1999) had similar success, reaching number 3 on the R&B charts and number 15 on the Hot 100. It also featured the track "Promise", which reached number 1 on the R&B charts and number 9 on the Hot 100.

The group's third release, Jagged Little Thrill, was released in 2001 and went platinum. Its success was in large part, due to the up-tempo "Where the Party At" which reached number 1 on the R&B charts and number 3 on the Hot 100, the group's highest-charting single.

Jagged Edge's fourth album, Hard, was released in 2003 and went gold. The album's single "Walked Outta Heaven" performed well on the charts, reaching number 6 on the Hot 100 and number 2 on the R&B charts.

Jagged Edge's fifth album, Jagged Edge, was released on May 9, 2006, by Columbia/Sony Music Urban and it went gold. It featured the hit urban single "Good Luck Charm". Also released on November 21, 2006, was The Hits collection featuring Jagged Edge's biggest hits plus a few album tracks. The album shared the single "Stunnas" that's also on the Jagged Edge album as a bonus track.

Jagged Edge parted ways with Columbia Records shortly after the release of their self-titled fifth album and signed back with Dupri. Dupri re-signed the group to So So Def through Island Def Jam, which handles the distribution for So So Def, and where Dupri was president of the urban division. The group was also granted their own record label called 581 Muzik Groupe which was credited on their album, Baby Makin' Project.
