Ryczące Dwudziestki is a Polish band established in 1983 in Bytom, Poland. They play folk music and shanties. The name of the band, which translates as "Roaring Twenties", came from the Roaring Forties (the latitudes between 40°S and 50°S famous for strong westerly winds) and the age of the musicians (who were 20 in 1983). .
