While musicians Al Petteway and Amy White are not native to the Old North State, they are now much-revered residents of Asheville.

The duo will be on the porch of the Postmaster's House, 204 E. South Street, in downtown Aberdeen.

"Their range and repertoire is extraordinary," says a spokesman. "It may well be called all things acoustic."

Their sound is a blend of original, traditional, contemporary Celtic- and Appalachian-influenced music. They offer a repertoire that includes extensive instrumental work as well as a fine touch of vocals and features acoustic guitars, mandolin, Celtic harp, banjo, Irish bouzouki, piano and world percussion..

Petteway directs the guitar program at the esteemed Swannanoa Gathering in Black Mountain and also maintains a nationwide performance and recording calendar.

Al and Amy were artists-in-residence at the Kennedy Center Millennium Stage and at Warren Wilson College. Their signature sound is heard often on NPR, satellite, Internet and independent radio stations. Their music has also been used in soundtracks for independent films, including Ken Burns' documentaries on "Mark Twain" and most recently, "The National Parks -- America's Greatest Idea."

While living in the Washington, D.C., area, Al and Amy won a grand total of 50 Wammies from the Washington Area Music Association in the Folk, Celtic and New Age categories as well as five separate grants from the Maryland State Arts Council for both composition and instrumental performance.

In 2001, Al and Amy received a coveted Indie Award in the acoustic instrumental category from the Association for Independent Music for their album, "Gratitude." In 2005, Al received a Grammy Award from NARAS (National Association of Recording Arts and Sciences) for his solo fingerstyle guitar contribution to the pop instrumental compilation, "Pink Guitar."

In the autumn 2002, the couple packed up their cats, their music studio, photography equipment and art supplies and moved from Takoma Park, Md., to the beautiful Blue Ridge Mountains of Western North Carolina.

They say that the rich cultural and natural history of their new home has been a large influence on their more recent recordings, "Winter Tidings," "Golden Wing," "Acoustic Journey" and "Land of the Sky: Musical Inspirations from the Southern Appalachians."

The show starts at 6 p.m. Admission is $9 at the door with cash or check, or online by debit or credit card at www.theroosterswife.org. Children under 12 are admitted free of charge.
