Festival of New Songs (, FENS; previously ) is a festival of new and as yet nonaffirmed musicians from Slovenia and abroad. It is the only festival in Slovenia where not only adults but children and teenagers compete too. It takes place in July each year in Izola and Koper and is broadcast by main Slovene television and radio stations. In its more than 20 years of history more than 500 rock, jazz, metal, and pop performers from Slovenia and abroad (Italy, Croatia, and France) have participated, amongst them Kingston, Tinkara Kovac, Lara Baruca, Ylenia Zobec, Siddharta, Alya, Polona Furlan, Andraž Hribar, Monika Pucelj, Sound Attack, Aleksandra Cermelj, Mambo Kings, Nude, Botri, Maja Slatinšek, Johnny Bravo, Foxy teens, and Eva Cerne. Its long-term mission is to promote Slovene music, to establish the international cooperation and the exchange with other European countries.

The Fens, also known as the , is a naturally marshy region in eastern England. Most of the fens were drained several centuries ago, resulting in a flat, damp, low-lying agricultural region.
