The EP was recorded in 2004, while Danny Grey was still in high school. It was planned to be the debut EP of his own persona, Unnamed, until he attended Grey Academy, in which he met his future bandmates, and the EP was scratched. He originally had the EP's tracks hosted on a custom website, in which he later removed. Octo EP was going to be released as a hype-up for the band's first studio album, Forever Nothing, but three of the five tracks were leaked. It was officially released on October 1st in 2015.
