HeartbreakJagged Edge began their mainstream recording career with the single "The Way That You Talk". They followed this in 1998 with the album, A Jagged Era which managed to go gold featuring the singles "I Gotta Be" and "The Way That You Talk". "I Gotta Be" which was written by the twins, 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 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 #11 on the Hot 100. The album's second single, "He Can't Love You" (released January 18, 2000) 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 2000, reached #1 on the R&B charts and #9 on the Hot 100. The album's lead single, "Keys to the Range", however was the sole flop from the album.Jagged Little Thrill and HardThe 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 #1 on the R&B charts and #3 on the Hot 100, the group's highest charting single. Two other singles ("Goodbye" and "I Got It 2") failed to become hits at radio.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 #6 on the Hot 100 and #2 on the R&B charts. The follow-up single, "What's It Like" did not fare well on the charts, thus ending the promotion for the album.During this same year, Dupri and So So Def left for Arista Records but Jagged Edge decided to stay with Columbia.Jagged Edge and Baby Makin' ProjectJagged Edge's fifth album, Jagged Edge, was released on May 9, 2006 by Columbia/Sony Music Urban and it went gold.
