Video: KING DIAMOND And SLAYER's KERRY KING Discuss How They Got Into Heavy Metal

Kerry King of SLAYER and legendary Danish heavy metal singer King Diamond (MERCYFUL FATE, KING DIAMOND) recently sat down for the latest episode of Noisey's "Back & Forth" series. Watch the two go into full nerd-out mode over how they got into heavy metal, making instruments out of rubber bands, and carving logos into flesh.

Kerry King has previously stated that he and fellow original SLAYER guitarist Jeff Hanneman were big fans of MERCYFUL FATE when SLAYER recorded the album "Hell Awaits", so much so that the LP was very influenced by the Danish heavy metal act.

MERCYFUL FATE's last studio album, "9", was released in 1999.

MERCYFUL FATE will be remembered for its unquestionable mark on the history of metal with its innovative sound, complex arrangements, memorable melody, and its influence on bands that later took the genre to new heights.

In 1998, METALLICA paid tribute to MERCYFUL FATE by recording a medley of classic MERCYFUL FATE songs on the album "Garage Inc." Entitled "Mercyful Fate", the medley included parts from "Satan's Fall", "Curse of the Pharaohs", "A Corpse Without Soul", "Into the Coven" and "Evil".

Lars Ulrich of METALLICA (a fellow Dane) played drums on a new version of MERCYFUL FATE's "Return of the Vampire" on the "In the Shadows" album, which came out in 1993.

Asked by Full Metal Jackie if he feels at all uncomfortable when fans share the impact MERCYFUL FATE had on them, King Diamond said: "It's great to hear. I mean, I was very lucky the other day. I went and saw my friends in VOLBEAT play here in Dallas. And ANTHRAX was supporting. I met [ANTHRAX guitarist] Scott Ian before, but I met all of [the ANTHRAX guys] this time around and got to really talk to them. And what an amazing bunch of guys. I mean, really great human beings — nice people. It was amazing. And they just played and put on an amazing show. So it was a very good evening, and it was great to meet [them]. And they also were talking about: 'Hey! Let's do [MERCYFUL FATE's] 'Evil'.' [And I said] 'Okay, I can do 'Evil' in my sleep, so we can do that, if you want to.' And then one of the other guys said: 'Hey, there's a little more to it than just that.' It can quickly go wrong if you have not tested it properly. So some other time we'll do it. But I remember, the drummer [Charlie Benante] said that he could play the entire 'Melissa' album, if need be. So it's nice to hear that people are really that into that old music still."

SLAYER's new album, "Repentless", was released on September 11 via Nuclear Blast.
