DEXTER — Amy Gallatin and Stillwaters will play their acoustic country and folk with a touch of bluegrass music at the Wayside Theatre/Grange at 7 p.m. Saturday, according to a Wayside Theatre press release.

The powerhouse duo of Amy Gallatin and renowned resophonic guitarist Roger Williams joined forces a few years ago to explore their mutual love of country standards, served up with an acoustic treatment in the bluegrass vein. The result is a toe-tapping blend of heartfelt vocals, soaring harmonies and red-hot picking, traditional yet modern and distinct.

Gallatin has been a staple on the acoustic music scene since her arrival in New England from Montana in 1993 with her shimmering, heartfelt vocals and quality song selections. Veteran bluegrasser Williams is long known for his masterful touch on the resophonic guitar during his tenure with White Mountain Bluegrass, Southern Rail, Blue Diamond and the New England Bluegrass Band. Now Williams is coming into his own as a vocalist and songwriter. Together Amy and Roger blend their voices in classic country duets old and new along with showcasing many of Roger’s originals.

Americana radio host Ed McKeon says: “Amy’s vocals, with the power and tone of her voice, are tempered by Roger’s baritone which has been sanded smooth by cigarettes and, shall we say, maturity. The song selections are perfect, the harmonies glorious, the sentiments wonderfully maudlin (like any good old country song),” according to the release.

The two are enhanced by Roger’s son, Berklee College of Music student JD, who — in the time-honored tradition of musical consanguinity — complements his father’s style perfectly. Completing the quartet is veteran bassist Eric Levenson, formerly with Joe Val and the New England Bluegrass Boys and later with Boston City Limits.

Admission cost $10. For more information, call 924-5711, 277-3733 or email WaysideGrange@yahoo.com.
