Neopagan music is music created for or influenced by modern Paganism. Music produced in the interwar period include efforts from the Latvian Dievturība movement and the Norwegian composer Geirr Tveitt. The counterculture of the 1960s established British folk revival and world music as influences for American neopagan music. Second-wave feminism created women's music which includes influences from feminist versions of neopaganism. The United States also produced Moondog, a Norse neopagan street musician and composer. The postwar neopagan organisations Ásatrúarfélagið in Iceland and Romuva in Lithuania have been led by musicians.
