Brian Wilson performs at 2005 Montreux, Switzerland, jazz fest.

The Newport Folk Festival is picking up good vibrations.

The festival producers announced Monday that Brian Wilson, a founding member of the Beach Boys, is joining the Rhode Island festival's lineup. He'll headline an evening performance on Aug. 1 at the International Tennis Hall of Fame.

The festival continues Aug. 2-3 at Fort Adams State Park.

Wilson is the latest big-name act added to the festival, which already includes Jimmy Buffett, Trey Anastasio, the Black Crowes and reggae artists Stephen and Damian Marley.

The festival is under new management and has branched out beyond more traditional folk this year. Organizers are hoping their roster of popular performers can produce a sellout.

The festival marks its 50th anniversary next summer.
