The Shook Twins and John Craigie may be the perfect season openers for the Sisters Folk Festival’s Winter Concert Series, which kicks off Saturday in the Sisters High School auditorium. The Portland artists are regulars in Central Oregon: The Shook Twins were just at 10 Barrel Brewing Co. in September and also played last year’s Newberry Event, while Craigie played a fundraiser for Cascade Youth & Family Center at the Domino Room in December. They straddle the boundaries of bluegrass, folk and indie rock, a winning combination around here (and especially with the SFF crowd). With that said, fans can expect some new sounds at this show. The Shook Twins are prepping their fourth studio album and first in nearly five years, “Some Good Lives,” due in mid-February; early singles “What Have We Done” and “Stay Wild” put more emphasis on the titular twins’ groovy rhythm section than ever before, pushing the group into psych-rock territory.

The Shook Twins, with John Craigie: 7 p.m. Saturday; $22.50 plus fees, $15 plus fees for ages 18 and younger; Sisters High School, 1700 McKinney Butte Road, Sisters; sistersfolkfestival.org or 541-549-4979.
