James Mattern (of Open Grave Records/Divine Metal Distro) is compiling a book chronicling Christian metal in its various forms. The book, entitled A – Z Discography of Christian Heavy Metal, seeks to be “a complete discography listing every track recorded by over 500 groups [including] member line-ups, catalogue numbers, demo recordings, compilation recordings [and] recommended must-have recordings.” The project is being funded through kickstarter, and you can read more about it at kickstarter.com/projects/deathvalleyjim/a-z-discography-of-christian-heavy-metal.
Although James Mattern is behind the project, it is unclear who is helping compile the information.
