Jagged Edge

With their yearning ballads and amorous uptempo hits, Jagged Edge round the bases of R&B with ease.

Identical twins Brian and Brandon Casey teamed with church friend Kyle Norman and emerging singer Richard Wingo in mid-’90s Atlanta—a prime time and place to be taken under the wing of Jermaine Dupri.

The So So Def label boss helped the quartet concoct a can’t-lose formula: sing from the heart, convincingly and masterfully, over any type of production, from carnal grooves to celebratory jams.
