Show HN: Kolibri, a DIY music club in Sweden

https://kolibrinkpg.com/
143•EastLondonCoder•1w ago
We’re Maria and Jonatan, a married couple running a small music night in Norrköping, Sweden, called Kolibri.

It’s not a software project. We run it through our own small Swedish company, pay artists, and do the operations ourselves. We do one night a month (usually the last Friday) in a restaurant venue called Mitropa. A typical night is about 50–70 paying guests. The first years it was DJs only, but last year we started doing live bands as well.

We made a simple site with schedule plus photos/video so you can see what it looks like: https://kolibrinkpg.com/

On the site:

  * photos and short videos (size/atmosphere)

  * the kind of acts we book (post-punk, darkwave, synth, adjacent electronic)

  * enough context to copy parts of the format if you’re building something similar locally

  * for the tech-curious: we built our own ticketing system (first used in February) and a media ingestion pipeline for Instagram and external photographers
How it started was accidental. I was doing remote music sessions with a friend in London (Ableton projects back and forth on FaceTime), ran out of beer, and walked into the nearest place. I got talking to Nahir, who runs Mitropa, and floated the idea of running a DIY music night there. He was up for it.

What made it take off was doing things in person. People will show up alone if they trust the room. Maria ended up doing a lot of that work: greeting newcomers, noticing who looks uncertain, and setting a tone where people treat each other decently.

Maria didn’t come from a DJ background. Klubbvärdinnan started as a joke name at Kolibri and then became her DJ moniker. She got good quickly, and after a first gig outside our own night she started getting booked elsewhere too.

Marketing-wise, what worked best was very analogue: walking around town, visiting local businesses we genuinely like, buying something, introducing ourselves, and asking if we could leave a flyer.

In the beginning we weren’t sure how to present it on social media. So we filmed headphone walks: one person walking through town listening to a track we picked. It looked good, people wanted to be in them, and afterwards we’d buy them a couple of drinks and actually talk. That turned a social media interaction into a real connection. It was a bit of luck, but it worked.

Questions welcome about what worked, what failed, costs/logistics, and what we’d do differently if we started over.

A few concrete mechanisms that made this work (happy to expand):

  * “Host layer”: greeting newcomers + making it safe to arrive alone mattered more than we expected.
  * Curation as governance: coherent music changes how people behave in the room.
  * Offline outreach outperformed posting: visiting local businesses in person built trust faster than Instagram.
  * Scale changes the social physics; we stayed small on purpose.
Curious if anyone here has built local repeatable formats (meetups, reading groups, hackerspaces), what made them stick?
ChadNauseam•1w ago
Not against AI, but I think you would find this post to be better if you didn't use AI to write it. They are not quite at the point yet where they generate something interesting enough for most people to want to read. Additionally, it goes somewhat counter to your stated goals. You (or chatgpt) said:

> People return when they feel recognised and when the night has a consistent identity.

But there's no identity to your post, because it doesn't feel like it was written by a person. Try writing it yourself! It’s boring, but it builds trust because it’s human, not algorithmic.

Anyway, congrats! I used to be a little bit into the DIY music scene in Chicago. Super cool to see other manifestations of it around the world

embedding-shape•1w ago
I don't think it's AI, they're just Swedes, we talk in a kind of boring way I suppose, and directly translating it into English usually makes it read kind of "stiff". I don't get the same feeling as you, but might be I'm just used to it.
Gooblebrai•1w ago
It's definitely AI. There are many tell signs
rrr_oh_man•1w ago
Agree.

The paragraph when I stopped reading:

> What we built isn’t an app. It’s a repeatable local format: a standing night where strangers become regulars, centred on music rather than networking.

EastLondonCoder•1w ago
OP here (Maria & Jonatan). This took off while we were asleep.

Maria is the creative force and writes Swedish very well. We used ChatGPT as a bouncing board to translate/tighten the English and get the story across. The piece reflects what we do, but in hindsight it probably ended up a bit over-polished.

Happy to answer questions.

tomcam•1w ago
> early on we needed Instagram content that could show music visually without filming crowds in a club. We started filming headphone-walk clips: one person, headphones on, walking through town to a track we chose.

Brilliant. Fantastic example of constraints producing richly creative results.

EastLondonCoder•1w ago
Thanks. The idea came from trying to visualise “listening to music” in a way that actually works on social media without filming crowds inside a club. The constraint forced a better format.
grokx•1w ago
A few years ago, I started again to attend regularly to concerts, and often in small / mid size local rooms, with an audience from perhaps 50 to a few hundred people.

Those are much more meaningful to me than those giant stadiums where you watch the band on giant screens. These thoughts will seem obvious, but smaller spaces with a limited audience are really warmer. You feel much closer to the artists, you are sharing emotions, sometimes the artist comes playing or singing in the middle of the audience. Things happen! A guitar string breaks, a drum falls, the singer goes out of tune. This is real live music!

raves are also severely underrated among autistic nerds
EastLondonCoder•6d ago
We do agree with this, we both prefer attending small gigs ourselves for that exact reason. Also, all bands has to start somewhere, it takes many small gigs to create an audience and develop their craft. Writing and producing songs is one thing but there is no substitution to the experience to see what moves in people listening live. The majority big stadium bands started with endless small non paying gigs, this is the foundation of the music business.

Might travel down from Stockholm in a couple of months. Too few nights like this in Sweden (Hosoi can be quite good though).
EastLondonCoder•1w ago
Nice, you’d be very welcome.

Strong spring lineup. Tonight is Hidden Lines, end of Feb Sydney Valette (Paris), and 20 March Liminal Project (UK) + Yugoslavia (ES) with Inåt Bakåt Records. On 11 April there’s a one-day festival in Norrköping (Kallsup, Poloklubben, Zack Zack Zack, etc.).

We’ve been experimenting a bit with how much we pre-announce (small room, and we don’t want to spread people too thin), but the schedule on the site is the best place to check. Instagram is our main outreach: @kolibrinkpg

I'm intrigued but also very confused on what this is about. Posting so I can looking into that later

Totally fair. It’s a real monthly music night, not software.

The Show HN part is the site + media (so people can see the scale/atmosphere), and the thing we’re trying to share is the operating model: how you get strangers to show up alone, feel safe, and come back, without big budgets.

proxysna•1w ago
Sick, nice to see something like that in the neighborhood. Too late for me to pay a visit today, but see you in 4 weeks!
EastLondonCoder•6d ago
You’re very welcome! Next one is Feb 27: Sydney Valette (Paris) + Coppia (Eskilstuna).

This is a very different ShowHN and I love it.

Best of luck going forward.

How did you choose the name? (I know Colibrí is hummingbird in Spanish - here in Guatemala, lot's of places with Colibri in the name).
zyber•1w ago
Kolibri is hummingbird in Swedish as well
EastLondonCoder•6d ago
As the other poster commented Kolibri is hummingbird in Swedish. The name was inspired by 2 things. A feeling of lightness and ease connected with carefree summer nights and also the intros of all versions of pacific by 808 state.
olelele•1w ago
Hej! Ole här, var hos er för nåt år sedan. Kul att se er här!!

Kul att höra från dig! Det är många olika personer runt Kolibri som känner dig från Berlin som t.ex. Henrik Maneuever så det var extra kul när du besökte oss.

> See you in the smoke & haze

Aha, I recognise this as a direct translation of what I used to see DJs and club promoters writing in GBG and Sthlm — ses i dimman!

EastLondonCoder•6d ago
Haha, almost, we add an extra word and some signifiers.

"Vi ses i röken och dimman! "

It actually means something specific. We tend to use a smoke machine a lot on our nights, one time the police showed up because they thought the place was on fire. The symbols at the end signifies the electricity of nights and the headphones is of course a reference to our social media headphone walks.

This is fixed catchphrase we use in all our communications.
