Whether he was destroying hotel rooms, marriage vows, or his drum kit—both literally, by setting it on fire and metaphorically with his virtuosic pounding—Led Zeppelin’s explosive drummer was a wild man with a very dark side.

Marlene Dietrich’s film titles say it all. Blonde Venus. The Scarlet Empress. And perhaps most of all: The Devil Is A Woman.
