Ben Boye is a Chicago-based multi-instrumentalist who has worked with many jazz, indie rock, and folk musicians. He has added pianos, synthesizers, pump organs, and occasionally autoharp, to recordings for artists as wide-ranging as outsider folkie Bonnie Prince Billy and garage iconoclast Ty Segall.

Early in his run, Boye was featured on a track on glitch-folk artist Khonnor's 2004 debut, Handwriting, but he became far more prolific during the 2010s, appearing on several albums by Bonnie Prince Billy, the Cairo Gang, and Ryley Walker. He also played autoharp in Joshua Abrams' improvisatory ensemble Natural Information Society. In 2016, he appeared on guitar legend Harvey Mandel's album Snake Pit. He also participated in Chivalrous Amoekons, an indie folk supergroup (including Will Oldham, Angel Olsen, and the Cairo Gang's Emmett Kelly) that performed covers of songs by the Mekons. Boye played piano on Ty Segall's eponymous 2017 full-length. At Will Oldham's recommendation, he collaborated with Mark Kozelek, first on Jesu and Sun Kil Moon's 2017 album 30 Seconds to the Decline of Planet Earth. Later in the year, Boye and Kozelek recorded an album with Dirty Three drummer Jim White. Three years later the trio returned with a second volume of their collaborations, aptly titled Mark Kozelek with Ben Boye and Jim White 2. ~ Paul Simpson, Rovi
