Mac Sabbath was formed in early 2014, debuting online through a (since removed) demo recording of a "Children of the Grave" parody entitled "Chicken for the Slaves", which was posted to an official Mac Sabbath YouTube and Facebook account on March 26, 2014. The members of Mac Sabbath are musicians from the Los Angeles rock and metal underground, though the band has preferred to maintain total anonymity behind their characters and an elaborate backstory which alleges the band comes from a "delicate part of the space time continuum". Mike Odd, lead singer of the Los Angeles hard rock band Rosemary's Billygoat, publicly acts as the group's manager and speaks on their behalf in press releases.
