Earth A.D./Wolfs Blood is the last album released by American horror punk band The Misfits 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 harder and faster than their previous releases. Since its release it has often been referred to as "Earth A.D." amongst fans.
Originally released as a 9 song LP, it was later issued with the three tracks of the Die, Die My Darling EP incorporated into the track listing: "Die, Die My Darling", "Mommy, Can I Go Out and Kill Tonight?" and "We Bite".
Glenn Danzig has said that the tracks "Bloodfeast" and "Death Comes Ripping" were originally intended for Samhain's first release, but were added to what would be the Misfits' final record in a last-ditch effort to save the band.
