Jack Doom, 51, was born in Korea, while his father was stationed there, but grew up in Hawaii. He returned to Hawaii after attending college on the mainland, planning to “hang out for a couple of years,” but never left.

Instead Doom (his professional nom de plume) got into hard rock and heavy metal music, first as a musician and then as a promoter.

Doom’s company, Underworld Events, is Hawaii’s foremost presenter of metal, hardcore and punk rock concerts. Groups brought to Hawaii include Municipal Waste, Killswitch Engage, Red Jumpsuit Apparatus and the Vandals.

JOHN BERGER: How did you get into concert promotion?

JACK DOOM: About 15 years ago I was in a band, and I started doing shows to get my band better shows. Word got out, and booking agents and bands started calling me.

I figured out what I needed to do local shows, but when I decided to bring out national acts, Nikki Robinson from Goldenvoice spent an afternoon showing me what I needed to do with all the stuff that I had never had to deal with.

It was awesome of her, and that’s one of the reasons I’m able to do what I’m doing now.

JB: What’s the biggest change you’ve seen since you started doing shows?

JD: The audiences getting older. These days I see people from their teens up to their 50s and 60s.

JB: What’s your next big show?

JD: Emmure this Thursday (Feb. 22) at Anna O’Briens. They’re a deathcore band, very heavy, and this is the first time that they’ve been out here in about seven years.

Anna O’Briens is a new venue for us. They’ve upgraded their facilities, they’ve gotten all new gear and they are embracing metal and punk music.

JB: What would you like to do after that?

JD: I’m looking for a place to do all-ages shows. There’s obviously a lot of liability issues involved, but when I was younger I was bummed if I couldn’t get into a show because I wasn’t 21, and so I want to do all-ages shows.

JB: What do you like to listen to that isn’t work-related?

JD: I fluctuate between Duran Duran and Slayer, both ends of the spectrum.

JB: You’re adamant about keeping your personal life and your birth name private. Why is that?

JD: Wherever I bring in a big act, I hear from people I haven’t heard from in years claiming that they’re my best friend and, oh yeah, can I have free tickets to the show?

It’s a problem now, but it would be worse if they could harass me at home.
