NEWPORT, R.I. (AP) — The three-day Newport Folk Festival is opening in Rhode Island.

New Zealand folk comedy duo Flight of the Conchords is headlining Friday, with acts including case/lang/veirs, the Arcs and the Violent Femmes also scheduled to perform at Fort Adams, a state park that overlooks Narragansett Bay.

Musicians including Patti Smith, Norah Jones and Ryan Adams appear Saturday. On Sunday, Alabama Shakes and Elvis Costello are among the acts scheduled to wrap up the weekend.

It’s the 57th anniversary of the first folk festival, which is best known as the place where Bob Dylan went electric in 1965.

It has gained in popularity in recent years and sold out even before the lineup was announced this year.

The Newport Jazz Festival will be held next weekend.
