Here are 50 of the most controversial hard rock and metal album covers of all time.

Rock and metal are no strangers to provocation, whether it's a deliberate attempt to be shocking for the sake of generating controversy, or it's just some artistic expression that happens to be quite extreme.

We've kept a focus on hard rock and heavy metal, so it means you won't see the controversial cover Yesterday and Today artwork from the likes of The BeatlesYesterday and Today.
