Over recent months Callahan and Bonnie "Prince" Billy have been recruiting guests to feature on their covers. After linking with Wand’s Cory Hanson on a cover of "Night Rider's Lament" last week, the duo have recruited Six Organs of Admittance, aka Ben Chasny, to contribute to their cover of Palace's "Arise, Therefore".

"Arise, Therefore" is a familiar track to Bonnie "Prince" Billy, real name Will Oldham, who released the track under his Palace moniker in 1996, but the cover released today (25 January) sees Callahan take the lead on vocals.

Other covers by Callahan and Oldham that have been released over recent months include Little Feat's "I've Been the One" with Meg Baird, Robert Wyatt's "Sea Song" with Mick Turner, Steely Dan's "Deacon Blues", Billie Eilish's "Wish You Were Gay" with The High Llamas’ Sean O’Hagan. Other covers by Callahan and Oldham include their version of Yusuf/Cat Stevens' "Blackness of the Night" with AZITA, and a cover of Hank Williams Jr.'s "O.D.'d in Denver" featuring Matt Sweeney.

Bill Callahan and Bonnie "Prince" Billy's cover of "Arise, Therefore" featuring Six Organs of Admittance is out now on Drag City.
