Book of Hours was first released by Les Disques du Crepuscule in 1989. Guest musicians on the album include Tuxedomoon members Steven Brown, Luc van Lieshout, Paul Zahl and Ivan Georgiev, as well as Ludus guitarist Ian Devine, while the single was a surprise funereal cover of El Paso by Marty Robbins. The CD has now been remastered with five bonus tracks, including Bay Bridge, the rare film soundtrack contribution Blackout and two tracks (Cosey Little Planet, Burnsday) from the rare single Orphans, released in a limited run of 100 copies in 1997. The CD also features all-new artwork.
