Thy Art Is Murder, Fit For An Autopsy, and Malevolence have all posted the same teaser to their Instagram profiles. Whatever they are, Thy Art Is Murder notes that it's coming at midnight on March 10. So it's probably safe to assume this is some sort of three-way split, but I guess we'll find out in a few days.
Thy Art Is Murder and Fit For An Autopsy are no strangers to doing splits with one another, as they both contributed to the Depression Sessions three-way split alongside The Acacia Strain in 2016. For that one, all three bands contributed one original song and one cover. So maybe it's another Depression Sessions split?
