Music

Love songs are like the meat and potatoes of most rock and pop music, but sometimes you need something different. For the band Delta Rae from Durham, N.C., inspiration for new material comes from stuff like graveyards and being stuck in the wrong job.

Delta Rae is a six-piece band that includes three siblings: Ian, Eric and Brittany Holljes. Their music is like a kind of modern folklore.

Singer-songwriter Tim Easton makes his third appearance on Mountain Stage, recorded live on the campus of the University of Alaska at Fairbanks. Originally from Ohio, Easton has traveled extensively since leaving his college-era bands to concentrate on a solo career.

David Wax Museum fuses traditional Mexican and American folk music into what the band calls "Mexo-Americana" — a style that's lively and unique. David Wax and Suz Slezak, the band's core members, met in Boston in 2007. After spending summers working with Quakers in rural Mexico, Wax spent a graduate fellowship year studying the local music of Mexico.

Pianist Cyrus Chestnut took his time making a name for himself on the jazz scene: For a decade starting in the mid-1980s, he apprenticed as pianist for Jon Hendricks, Betty Carter, Donald Harrison and Wynton Marsalis. But since then, he's toured the world and recorded 15 albums as a bandleader.

In this performance and interview, Cyrus describes his gospel roots and his discovery of jazz, and discusses how he approaches interpreting other composers' music.

Set List

• "Tonk"
• "Polka Dots And Moonbeams"

Singer-songwriter Iris DeMent was born the youngest child of a large Pentecostal family in rural Arkansas, and later moved to Southern California. DeMent grew up listening to traditional country and gospel music, which influenced her roots-folk sound, though she was 25 when she wrote her first song. It would take another five years for her to release her first album, Infamous Angel.

The string-laden indie-folk band Horse Feathers makes its second appearance on Mountain Stage, recorded live on the campus of the University of Alaska at Fairbanks. Centering on the soft vocals and guitar of Justin Ringle, Horse Feathers' "chamber folk" sound is crafted with the assistance of cellist Lauren Vidal, violinist Angie Kuzma, Dustin Dybvig on drums and piano, and Nathan Crockett on violin, mandolin and the musical saw.

For all the plot development in the series' infancy, last Sunday's episode of Treme was unusually saturated in live performances. The second half of the episode, especially, seemed like one concert after another. Here with me to recap the musical goings-on is WBGO's Josh Jackson.
