The band's sound and repertoire bring out Douglas's delicate, lyrical side; his gentle original tunes are complemented by an unusual mix of American folk songs and traditional hymns. The group is joined on much of the record by singer Aoife O'Donovan; best known as a member of Americana group the Crooked Still, she's been turning up all over, including on a solo record by Punch Brothers banjoist Noam Pikelny and on Yo-Yo Ma's Goat Radio Sessions (she also plays a solo gig at SPACE in Evanston on August 21). She's got a lovely voice, precise pitch control, and sublimely liquid phrasing, but she isn't included here to underline the project's connection to rural American music—instead, like the rest of the performers, she finds her own ethereal spin on it. Below you can hear O'Donovan on the opening track of Be Still: a version of "Be Still My Soul," a hymn by the great Finnish composer Jean Sibelius. For any Douglas fans thrown off by the sound of this track, don't worry—the album features plenty of high-level modern jazz, with especially sharp interplay on the three original pieces.
