UNITY — The Sweetback Sisters will fill the Unity Centre for the Performing Arts with rollicking country swing on Friday, Jan. 28.

Like their pseudo-sister role models, the Davis Sisters, the Sweetback Sisters sing country songs in close, surrogate-sister harmony and matching dresses. Their repertoire combines two of the Sisters’ passions: country music from before they were born and new interpretations of those traditions.

Making up the band are vocalists Zara Bode and Emily Miller and instrumentalists Jesse Milnes, Stefan Amidon, Ross Bellenoit and Peter Bitenc.

Sweetback Sisters’ debut EP, “Bang!,” was released in early 2007 and earned a spot on A Prairie Home Companion’s talent contest for twenty-somethings. The band released its first full-length album, “Chicken Ain’t Chicken,” two years later on Signature Sounds Recordings.

The show will begin at 7:30 p.m. Tickets, $17, may be purchased at www.unityme.org, For more information, call 948-SHOW or 680-5819.
