Horror Business is the second EP released by The Misfits. It was recorded in January-February of 1979 and was released by Plan9 Records in June of the same year. These songs were originally intended for release on a 5-track Who Killed Marilyn? 12-inch EP, but the band realized they couldn't afford a run of the 12-inch and settled on this 3-track 7-inch EP instead.
