Earth A.D./Wolfs Blood is the second "full-length" album (clocking in at less than 15 minutes) by the American punk rock band Misfits. It is the last album released to feature founding member and lead vocalist, Glenn Danzig. Danzig released it on his Plan 9 label in December 1983, two months after he played his last concert with the band. It was noticeably heavier and faster than their previous releases, showing more of a hardcore/thrash sound. Since its release it has often been referred to as simply "Earth A.D." amongst fans. The iTunes version of the album is titled as Earth A.D. / Die, Die My Darling.
