 "Carbon-Based Anatomy" EP is composed of six previously unheard tracks.However, the song "Carbon-Based Anatomy" is a reinterpretation of an older unreleased Æon Spoke single, "Homosapien".This was also done on Cynic's last LP, "Traced In Air", as the track "Integral Birth" was an interpretation of Æon Spoke's "When Sunrise Skirts the Moor."
