Brian McKnight

One of the most consistent and versatile adult contemporary R&B artists, Brian McKnight placed seven albums across 15 years -- from the early '90s through the first decade of the 2000s -- within the Top Ten of Billboard's R&B albums chart. Whether he wrote and produced for himself or collaborated with the likes of Diddy, the Underdogs, and Tim & Bob, he enjoyed moderate commercial success without ever quite becoming a superstar. This, along with a down-to-earth personality and a catalog heavy on mellow material, may have helped McKnight for the sake of longevity; he made his first mark during the tail-end of the new jack swing era and, nearly 20 years later, shared chart space with singers half his age. He holds a Grammy record for 16 nominations without a win.
