Headliners have been announced for the 33rd Annual Ann Arbor Folk Festival, Jan. 29-30 in Hill Auditorium.

Friday evening will feature Iron and Wine, along with a host of other artists who are known for pushing the boundaries of their art, bringing a progressive sound to the folk music scene. Saturday night will delve into the heart of folk and roots traditions, showcasing styles well known to Folk Fest audiences. Topping Saturday night’s program are Rosanne Cash and Doc Watson.

Work is continuing on finalizing the Folk Festival lineup, according to Ark Marketing Director Barb Chaffer Authier, with additional headliners and other artists to be announced soon.

Tickets for Ark members go on sale Monday. Tickets go on sale to the general public on Dec. 1. The event is a major fundraiser for The Ark, Ann Arbor’s nonprofit home for folk, roots and ethnic music.

Descriptions of the artists announced so far, provided by The Ark:

• Iron and Wine is singer-songwriter Samuel Beam, who came on the scene in 2002 with an acoustic album called “The Creek Drank the Cradle” that drew comparisons to Nick Drake and the late Elliott Smith. Later Iron and Wine albums have offered lush electric textures, but for his Folk Festival appearance, Beam will return to his acoustic-indie-folk roots.

"Upward Over The Mountain" - Iron & Wine

• Philadelphia’s Hoots and Hellmouth, also on the bill for Friday as a spotlight artist, is the duo of singer-songwriters Sean Hoots and Andrew Gray. They call their sound “new music for old souls,” and it has elements of alt-country, classic folk, and jam-band freedom. A performance at the 2006 Philadelphia Folk Festival put them on the map, and they’ve built a following since then pretty much just by taking their music on the road.

"You and All of Us" - Hoots & Hellmouth

• Rosanne Cash — with her then-husband, Rodney Crowell — essentially created progressive country music in the early 1980s. Cash is also a children’s book author; an essayist who has been published in The New York Times and the Oxford American; an editor; a producer and an activist on behalf of children. With all this in mind and on view, it’s easy to forget that she is also Johnny Cash’s oldest daughter. Now she has paid him homage in on her latest album, “The List,” on which she selected 12 pieces from a list of 100 country songs that her father gave her when she was 18 and that she’s always saved.

"Silver Wings" - Rosanne Cash Featuring Rufus Wainwright

• Singer and guitarist Arthel L. “Doc” Watson, who has played at four previous Folk Festivals, has received the National Medal of Arts, a National Heritage Fellowship and other honors too numerous to list. Born into a musical family, he attended the Raleigh School for the Blind, where he picked up the guitar and learned various other skills (he can make you a superb hand-caned chair should you happen to need one). He is considered one of the most influential guitarists of the last century. For example, playing fiddle tunes on a guitar is commonplace nowadays, but before Doc came along it was hardly ever done. The folk revival of the 1960s would have been hard to imagine without Doc Watson.

"Black Mountain Rag" - Doc Watson
