Anacostia was an American funk and soul band prominent in the 1970s. Named after the Anacostia neighborhood in Washington D.C., the band was best known for its smooth, R&B-infused sound and unique vocal harmonies, fronted by lead singer Van McCoy. Despite their relatively short-lived career, they made a significant contribution to the R&B genre with their hit single "On and Off," which reached number 24 on the Billboard R&B chart. Anacostia's music continues to be sampled and referenced in contemporary musical works, highlighting their enduring influence within the industry.
