Harold Melvin and the Blue Notes, featuring Sharon Paige, were a significant R&B and soul band known for their emotive and soulful sound during the 70s. The group, initially led by Harold Melvin, was notable for its inclusion of Teddy Pendergrass, whose powerful, expressive vocals became a signature element of their music. They were influential in the development of the Philadelphia soul subgenre, working closely with songwriters and producers Kenny Gamble and Leon Huff. Hits such as "If You Don't Know Me By Now" and "Wake Up Everybody," the latter featuring Sharon Paige, highlight their socially conscious lyrics and rich orchestral arrangements.
