From her base in Eugene, Oregon, Caitlin Jemma has forged a sound rooted in the traditions of bluegrass, old-time and folk. As such, her previous three records were mostly acoustic efforts with sparse production and tidy arrangements. But on her new album, “Love Notes,”  Jemma plugs in and lets loose.

The roots are still there — Jemma’s beautifully raspy voice is still the focus — however, she’s added an unmistakable and infectious swagger to her delivery. You can see the transformation for yourself in the video for her song “XXOO.”

If her cosmic country sound is vaguely familiar to your ears, it might be because the new album’s production was a collaboration between Jemma and Bart Budwig, who engineered and mixed the 10-song effort at his studio at the OK Theatre in Enterprise, Oregon. The cuts were recorded live with help from a combination of Jemma and Budwig’s backing bands (seven musicians in all).

“Love Notes” is due out May 1.

Jemma kicks off a string of tour dates throughout Oregon, Washington, and California at The Liquor Store in Portland on May 3.
