The Metal Box is a weekly web series posted each Friday where we discuss all things hard rock and heavy metal: news, videos, interviews, live concerts and more.

This week, we remember Playboy creator Hugh Hefner who passed away this week at the age of 91. Watch video above.

Playmates, rock stars, even civil rights activists are remembering the man that built an empire that played an important role in the sexual revolution. I figured why not honor Mr. Hefner on the Metal Box? I can't remember a fellow metalhead growing up back in the day that didn't thumb through the pages of Playboy magazine at one time, for the interesting articles of course. Originally started in 1953, the men's lifestyle and entertainment magazine has now grown into Playboy Enterprises, Inc. and it remains one of the world's best-known brands. R.I.P. to the great Hugh Hefner. An icon and influence to many.
