Elly Zuiderveld-Nieman (born 7 April 1946 in Hilversum, The Netherlands) and Rikkert Zuiderveld (born 5 February 1947 in Groningen, The Netherlands) are a Dutch acoustic singer-songwriter duo, rooted in the Dutch folk tradition. They met in 1966, having released a solo LP each, and started performing as a duo in 1967 and 1968. They were part of a sixties scene of Dutch singer-songwriters singing in their mothertongue. Boudewijn de Groot, Dimitri van Toren, Joost Nuissl and Ramses Shaffy were some of their musical acquaintances in this era.
