Bandcamp In October, Austin's brooding balladeer Bill Callahan teamed with equally enigmatic auteur Bonnie Prince Billy to release a surprise cover of Cat Stevens' "Blackness of the Night," with arrangements by Drag City labelmate Azita Youssefi. The singles have continued weekly since, each a new cover and collaboration, ranging from pop busters (Steely Dan's "Deacon Blues" with Bill MacKay; Billie Eilish's "Wish You Were Gay" with Sean O'Hagan) to more obscure (Johnnie Frierson's "Miracles" filtered through Ty Segall; Lowell George's "I've Been the One" with Meg Baird). Amid Lou Reed's "Rooftop Garden" and Hank Williams Jr.'s "OD'd in Denver," the duo also rolls out a deep Jerry Jeff Walker fascination with takes on "Little Bird," "Letter Sung to Friends," "I Love You," and "Night Rider's Lament." The arrangements spiral eclectic and provocative, hung across the balancing act of Callahan's low, methodical intonations and Oldham's creaking high lonesome. –
