The New Mexico duo, Moody Little Sister, will bring what they call “Southwestern Americana soul” to an upcoming performance at 8 p.m. Saturday, Aug. 31, to Vashon Center for the Arts.

Duo members Naomi Sparrow and Rob Stroup’s show is a celebration of Moody Little Sister’s latest CD, “Great Big Mama Sunshine,” which will have its official release on Aug. 31.

The album is the result of both a personal and musical journey.

Two years ago, Sparrow and Stroup uprooted themselves from Portland, Oregon, and moved to the town of Truth or Consequences, in rural New Mexico. Quickly establishing themselves in the small town, they found new friends, supporters and collaborators. They have also quickly received recognition in their newly adopted state. One song on the album, “Evelina,” was nominated in the singer-songwriter category for the New Mexico Music Awards.

“Big Mama Sunshine” is a 13-track collection of melodic, roots-influenced pop songs, with a sound that is a departure from the piano-pop of their 2016 debut album, “Wild Places.” In the new album, Sparrow has chosen a guitar over the piano.

“My new love for the desert is also coupled with my new love for the guitar,” said Sparrow on the shift in sound, adding, “We have finally landed on our sound after almost a decade of making music together.

Special guests Skybound Blue and Ara Lee James will open the show. Skybound Blue is an Oregon-based duo; James is a local soul singer and songwriter whose own duo, Stand and Sway, recently performed at VCA.

Tickets, ranging from $15 to $22, are on sale now at vashoncenterforthearts.org. The show is co-presented by islander Debra Heesch.
