The Genies were an American doo-wop and R&B group active during the late 1950s and early 1960s. Featuring notable members such as Roy Hammond, the group is known for their hit single "Who's That Knocking," which reached the top 20 on the Billboard R&B chart. Their harmonized vocal style, combined with classic doo-wop rhythms, helped define the sound of early rhythm and blues. Despite their relatively short career, The Genies played a significant role in the development of R&B music.
