GRAND JUNCTION, Colo. - Singer-songwriters and husband-wife duo Chris and Kim Lindell return Saturday, Sept. 22, to the Radio Room, 1310 Ute Ave., for a concert to benefit KAFM Community Radio."It's a fantastic venue," Chris said, of the radio station's 75-seat performance room. He and Kim performed there a year ago along with David Gans, musician and host of the syndicated Grateful Dead Hour radio program.For the Saturday performance, Lindell said they'll be playing "mountain folk" - music "inspired by the high mountains and vast, lonely deserts of the American West." He'll play acoustic and electric guitars; Kim will perform the acoustic guitar and bass. Both sing and write songs. "We'll be showcasing a bunch of new songs," Chris said.When writing lyrics, "we sort of take an interpersonal emotion and try to make it vague so it's not about us," Lindell said.Their style of "non-topical" songwriting is influenced by artists such as Townes Van Zandt, Jerry Garcia and JJ Cale, Lindell said. The Lindells, who live outside of Dolores, Colo., perform regionally at theaters and festivals - including next weekend when they play at the Mountain Harvest Festival in Paonia Sept. 29 at the town hall. They've opened for Cale who performed at the Rico Theater eight years ago. Occasionally, the duo plays with Bob Matthews, former producer and recording engineer for the Grateful Dead. Matthews learned of the Lindells after hearing their recording of a New Riders of the Purple Sage song "Last Lonely Eagle."Matthews has called the Lindells' music as "a gift to all, and most satisfying for your heart and soul."The duo is in the process of recording a new CD, expected to be completed by spring. They're also involved in a project with the Bera Chrome band, for whom the Lindells play rhythm.Tickets to the concert at the Radio Room are $15.
