When Jagged Edge first formed in their teens, they realized the sum of their group would be greater than its individual parts — an understanding that's been the main ingredient of their success for nearly three decades.
One of the most iconic groups of modern R&B, Jagged Edge — Richard Wingo, Kyle Norman, lead singers (and identical twins) Brian and Brandon Casey — is back Friday with their 11th studio album, “All Original Parts: Vol. 1.” The title of the 15-track project points to the group’s solidarity: They’ve never broken up or switched original members.
