What to Ask Before You Book a DJ in Seoul

Q: 2. What backup do you carry, and what happens if it fails mid-set?

Good: "Two players plus a laptop with the same library, a spare controller in the car, duplicate cables, and my music on two drives and offline. If a deck dies mid-track, you will hear a slightly early transition and nothing else."

The short answer: the questions that protect you are about power, timing, backup gear, and who is allowed to make a decision at 11pm when the schedule slips. Ask those four and you’ll filter out most of the people who can’t deliver your event.

I’ve been DJing in Seoul clubs since 2006, and I’ve been on both sides of this conversation: the one being hired, and the one brought in late to rescue a room where somebody else was hired badly. What follows is what I’d ask if I were booking me.

The questions most people ask, and why they’re not enough

Almost every enquiry I receive opens with three questions: are you free on this date, what do you charge, and what kind of music do you play. Those are reasonable. They’re also nearly useless as filters, because every DJ alive can answer them in a way that sounds fine.

Availability tells you nothing about competence. Price tells you nothing until you know what’s included. And “what do you play” invites a list of genres that any working DJ can recite. The person who is going to let you down can answer all three perfectly.

The four questions that filter

1. Walk me through your load-in and setup timing

A good answer sounds like: “For a 7pm start I am on site by 4:30, set and line-checked by 5:30, and I stay quiet until doors. If your venue has a loading restriction or a lift I need to book, tell me now and I will call them this week.”

A bad answer sounds like: “I will get there about an hour before.” An hour is enough time to plug in. It’s not enough time to plug in, discover the venue’s house system needs an adapter nobody mentioned, and fix it before your guests walk in.

This question works because it can’t be faked. Someone who has done a hundred of these has a routine and will describe it in specifics. Someone who hasn’t will describe it in vibes.

2. What backup do you carry, and what happens if it fails mid-set?

Good: “Two players plus a laptop with the same library, a spare controller in the car, duplicate cables, and my music on two drives and offline. If a deck dies mid-track, you will hear a slightly early transition and nothing else.”

Bad: “That has never happened to me.” It has happened to everyone who has worked long enough. Confidence isn’t the same as redundancy, and a DJ who has never had a failure is usually a DJ who hasn’t had many bookings.

3. Who owns the running order on the night?

This is the question nobody asks and everybody needs. Corporate events and weddings drift. Speeches run long. The CEO arrives late. Somebody needs the authority to move the first dance, cut a track, or hold the floor for ten more minutes.

Good: “Send me the run sheet a week out. I will flag where it is going to slip. On the night, name one person who can make the call, and I will take direction from them and nobody else.”

Bad: “Just tell me when to start.” That leaves you improvising in front of your guests.

4. What do you need from the venue that I should confirm now?

A professional will immediately hand you a short list: dedicated power, a table of a certain size, where the speakers can physically stand, whether there’s a sound limiter, what time the noise restriction begins. An amateur will say “just a plug.”

The sound limiter one matters a lot in Seoul, and I cover why in the piece on how Korean venues actually run.

The things clients almost never think to ask

These are the ones that quietly decide whether your night works.

Power, seriously. A DJ rig, a lighting rig and a coffee urn on the same circuit is how you find out what a breaker sounds like. Ask what’s already on that circuit.
Where the speakers physically go. Sound aimed into a low ceiling or a glass wall behaves completely differently. The right position matters more than the size of the box.
The volume conversation, in advance. Decide before the night whether this is a room where people talk over music or dance to it. If people are meant to dance, check how the venue is licensed: a bar or restaurant registered as a general restaurant may not let guests dance unless its district has an ordinance allowing it, which in Seoul means Mapo, Yongsan, Seodaemun or Gwangjin. Most disappointment traces back to nobody agreeing this in advance.
Do you need an MC, or just a DJ? They’re different jobs. Announcements, bilingual or otherwise, should be agreed and scripted, not sprung on the DJ at 9pm.
Language. In Seoul this is real. If half the room works in Korean and half in English, someone has to handle both, and it should be decided before the invitations go out.
The do-not-play list. More useful than a request list. Every company has songs that will land badly in that particular room, and only you know them.
Meal and break. A five-hour set with no break is a fifth hour that sounds like it.
Who is paying and when. Deposit, balance, overtime rate. Agree the overtime rate before the night, not at 1am when everyone is having a good time. Paperwork for overseas DJs: under the Performance Act, a public performance with even one foreign performer needs a Korea Media Rating Board recommendation in advance. Approval is near automatic (1,980 of 1,998 applications last year), but penalties run to three years or ₩30 million, and in October 2026 Seoul asked the government to relax the rule.

How to read the answers

You’re testing whether this person has a system. Specifics, times, named equipment and a willingness to tell you something inconvenient are all good signs. Reassurance without detail is the warning.

The single best question, if you only ask one: tell me about an event that went wrong and what you did. Anyone with real hours has a story and will tell it plainly. It’s the fastest way to find out who you’re dealing with.

What you get when the answers are right

A DJ who has walked your venue, or one like it, and knows where the power is before load-in day.
A rig that fits the room: two CDJs and a mixer on a compact stand for most events, powered speakers only when the house system won’t carry a party, all agreed and in the quote. Riders may now name the CDJ-3000X, AlphaTheta’s successor to the CDJ-3000, which adds built-in Wi-Fi and cloud streaming; ask which model the venue or hire company has before the night.
A single-page running order, owned by one person, that the venue and the MC work from too.
Speeches handled properly: microphone, walk-up music, and real silence.
A do-not-play list honoured without a debate, and a read on a mixed Korean and international room.

How we work

One more thing: I work for Korean clients and international ones in equal measure, and a lot of my nights are both at once. If your room is mixed, say so early. The music and the announcements can carry two audiences comfortably, but only if somebody plans for it rather than discovering it at eight o’clock.

For most events it’s me in the booth. For larger or multi-room jobs I bring in DJs I’ve worked with for years and I stay responsible for the night. You’re dealing with the person who plays, not an account manager who passes you to whoever is free.

If you’re planning something in Seoul, tell me about it here. Even if I’m not the right fit for your event, I’ll tell you what to ask the person who is.

Frequently Asked Questions

What should I ask a DJ before booking them in Seoul?

The most useful questions to ask a DJ in Seoul cover load in timing, backup gear, who owns the running order on the night, and what the DJ needs from the venue. Date, price and music taste are reasonable to ask but filter out almost nobody. Price in particular means little until you know what’s included, which is explained in this guide to DJ costs in Seoul.

What backup equipment should a professional DJ have?

A professional DJ should carry real redundancy, for example two players plus a laptop with the same library, duplicate cables and music on two drives available offline. If a deck fails mid track, the audience should hear only a slightly early transition. Saying that a failure has never happened is a warning sign, because it happens to everyone who works long enough.

How early should a DJ arrive before an event?

For a 7pm start, a well prepared DJ is on site by 4:30 and set and line checked by 5:30. Arriving an hour before is enough to plug in but not enough to fix a surprise, such as a house system that needs an adapter nobody mentioned. Venue loading restrictions or lifts that need booking should be raised early so the DJ can call the venue ahead of time.

What’s the single best question to ask a DJ?

The single best question is to ask the DJ about an event that went wrong and what they did. Anyone with real hours has a story and will tell it plainly. Specific times, named equipment and a willingness to say something inconvenient are good signs, while reassurance without detail is the warning.
