As the old saying goes, don't judge a metal album by its cover. When it comes to cover art, bands strive to present the coolest looking artwork they can afford. Some bands are able to make a memorable cover that will adorn T-shirts and back patches forever. Others, not so much. Of course, all cover art varies depending on the style of the music; a Ratt album cover looks far different than those of Cannibal Corpse. Regardless of the genre, no band is immune to bad cover art. From obscure acts to metal legends such as Black Sabbath and Anthrax, they have all released some real stinkers. Here are some of the most ridiculous album covers in metal history.
