Earth A.D./Wolfs Blood is the last album released by American horror punk band 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, showing more of a hardcore punk sound. Since it's release it has often been referred to as simply "Earth A.D." amongst fans. Hands down one of the most influential punk records ever made, period.
