Royalcash is an influential American hip-hop duo known for their pioneering work in electro and old school rap music during the late 1970s and early 1980s. Comprised of Michael Camacho and Michael Anthony Bryant, the group is most notable for their 1983 single "Radio Activity," which has become a definitive track in the history of electro-funk. Their style is characterized by heavy use of synthesizers and drum machines, alongside catchy, often socially-conscious lyrics. Their music has made significant contributions to the development of hip-hop, particularly in the realm of electronic music production.
