Have you ever felt this wildness inside of you?
Craving to find a scene for expression?
Like a wild boar running to mark its terrain?
Getting cheered and feared all at once
And being the true chief of the woods?
If this sounds tempting to you, then Kollibri might chirp you the right fit.
With this year's new STAGE "AU Sanglier", we offer you a safe space to express yourself in a complete free and artistic way.
100 % DIY, 100% authentic, 100% punk!
The ScEne Sanglier is a stage, where all kinds of short and sweet art, dance, music, acrobatics, poetry, comedy... performances are welcome,
not minding age, conditions or complicated pre-registrations.
We get you the spot, you do your stuff!
You will find us in the entrance next to the "BARDOISE" and "WILD SANDWICHES":
where you can ask Mr. Tadda Trash for further information on procedures (time slots, equipment...),
with beautiful 90s tracks awakening the real boar in you!
Just bring your ideas, flexibility, spontaneity and not too high expectations with you.
Why so serious...? Just be wild and free!
We are looking forward to seeing YOU!
There are many more small and big things happening at Koll An Aktioun 2026. Like the Jonn happi show, swing dance taster class or luciano pagliarini in the legendary setting of the bopebistro.
Some of what we've planned, we'd like to keep a secret for you to discover on the weekend itself.
Other things are still in the making - like our Transformation Station. What is a Transformation Station, we hear you ask? It's where the journey into the Koll universe begins. With shiny, fluffy, and sparkling materials, you can reinvent yourself from forgotten leftovers and become whoever you’ve always wanted to be. Enter as a wanderer of this world and leave transformed as a Kollibri. What exactly the Transformation Station will look like? We'll all discover it next weekend!

Maz Univerze - You put butterflies in my stomach, I think I'm gonna vomit (Vertical Music Video)
Maz Univerze emerged from a conservative small town and it took time for his beautiful, gory poetry to escape the drawer and for the pride flag to unfurl between metal posters. Today, his thoughts erupt in a raw fusion of alternative rap, soaked in emo-rock and metal influences. He mixes skillful rap with distorted screams and melodic hooks; crafting a sound that is as dark as it is hopeful.
When Maz and his two bandmates take the stage, they turn the crowd into a single, powerful marionette limb, a collective beast rising up against social injustice and urging every soul to embrace their shadows as much as their light.

ikan hyu
STAGE: LA Scierie
SUNDAY: 21h00
IKAN HYU - side fx (Official Video)
Ikan Hyu's explosive live shows have sent shockwaves through the European music scene: the way the duo transmits the energy of a 'whole band' with two people is as unique as the sound that emerges: glitchy, loud, beautiful, free, profound and unpredictable.
The two front women each play up to three instruments at the same time - Hannah uses acoustic and electronic drum elements, a kaossilator and a synth bass, while Anisa uses a drum pad and a self-designed electric guitar/keyboard hybrid, which allows her to play guitar and bass at the same time.
All the fishes in the sea, get away cuz here comes she: IKAN HYU.
SEED TO TREE
STAGE: Le Con’Casseur
SUNDAY: 20h00
Seed to Tree - I Wouldn't Mind (Official Video)
We all know them and we all love 'em: our very own indie rockers Seed to Tree traffic in an amalgam of shoegaze, folk, new wave and Bon Iver-tinged indie-pop that we are very happy to have at Koll 26!
Emerging in 2012, the group initially formed as a folk-oriented project around a group of childhood friends, their sense of camaraderie evident in their band name. Seed to Tree began to make waves in 2019 with the release of their well-received sophomore effort Proportions and touring Europe as well as opening shows for bands like Beirut or The Temper Trap. Refusing to rest on the laurels of these achievements, they continue to expand their cinematic brand of indie rock to stunning effect.

Man/Woman/Chainsaw - Only Girl
Rising from London’s DIY circuit, Man/Woman/Chainsaw is an orchestral art-punk six-piece known for their joyous and raucous live energy. They balance cinematic violin arrangements with sudden, chaotic bursts of noise—a sound they’ve dubbed "the thin line between pretty and noisy."
Following their breakthrough EP Eazy Peazy (2024), the band signed with Fiction Records (home to The Cure) and recently announced their debut album, Cannonball, set for release on August 7, 2026. Having already played over 150 shows—including major sets at Rock Werchter, Latitude, and Fusion—they have solidified their reputation as one of the most unpredictable and vital young acts in the UK. Let's give them a warm and loud welcome to Martelange!

LE VIBE - Sur la Grand-Route (Official Music Video)
bad luck baby
STAGE: la scierie
SUNDAY: 17h00
BAD LUCK BABY - NEVER HAPPENED WITH YOU
Hailing from Leeuwarden, a province in dutch Friesland, Bad Luck Baby is a five-piece powerhouse, the result of perfectly timed misfortune: vocalist Cath and drummer Ian met after both losing their wallets on a night out, setting the stage for Bad Luck Baby. The band embraces the unpredictable nature of life, the ups and downs translated into powerful, fiery alt-rock. Bad Luck Baby tells stories - about despair, happiness, and the human existence.
Taking cues from bands like Paramore, De Staat, and Wolf Alice, Bad Luck Baby has crafted a sound uniquely their own: tight guitar riffs meet gloomy synths and vocals full of raw emotion. The result is a well-oiled machine, delivering unmatched energy in a (thought-)provoking, resonating performance.
NEWS
DIN - K
Koll an Aktioun is the culmination of a year-long effort organized by over 30 fully active, volunteer Kollibris, spread across 12 working groups.
Officially, we have 11 groups but new ones occasionally emerge in response to fresh ideas and evolving missions.
In 2023, Din K was born out of a new concept: “Casa Di Kollibri” a gastronomical experience designed to stage social interaction through the simple joys of life:
Pizza, Vino & Amore (or Pizza, Party & Amore depending on the mood!).
That same year, we began collaborating with “D’Kollektiv”, an association based at the VEWA in Dudelange. We needed plates to serve our homemade pizza alongside fine wine (or grape juice). The plates? Crafted from recycled wood collected over 15 years ago and lovingly reactivated together with members of D’Kollektiv in their atelier.
At the same time, we were forced to vacate our storage barn which held all our festival gear: materials, decorations, boxes, and countless mysterious objects. Ferroforum asbl came to our rescue, offering temporary space in their atelier at Metzeschmelz in Esch-sur-Alzette. But we knew this couldn’t be a long-term solution. We needed a plan.
Inspired by the industrial aesthetic of the space, we conceived a new system: everything must fit on Euro-pallets. a global standard that revolutionized how we consume, transport, and manage logistics. This would allow us to plan and execute multiple relocations quickly, until we find a permanent storage solution.
Din K was born and since 2024, we’ve met regularly at VEWA, using D’Kollektiv’s atelier and machinery to co-create eco-responsible, handmade decorations and scenography for Koll an Aktioun.
Our motto?
Hands on! Be together, have fun, and let your creativity flow!
Koll-ca
On paper, a CA (Conseil d’administration) might just be the most unglamorous, boring and bureaucratic thing ever. Not with the Kollibris! Our association, Kollibri asbl, is somewhat the house in which Koll An Aktioun makes up one room. The idea is that the other rooms are filled with further activities, ideas, groups and gatherings that all reflect the core values that connect us all.
the CA is the cozy living room in which we meet +/- once a month in order to discuss what’s going on at the festival, what needs to be done, to update each AG (working group) with each other, drink a beer or two together and discuss what’s important to us and in how far the association and the festival reflect this.
Yes, we might sometimes get carried away in our discussions and the evenings might end later than anticipated, but: every single time every single one of us leaves the CA with new input, ideas and views. And that’s what this should be about: to challenge ourselves. But in a fun way!
VISOUNSWEEKND
Ce n’était pas un rassemblement de rêveurs éveillés dans un nuage de fumée, mais une réunion stratégique, créative et profondément ancrée dans le réel. Une dizaine de Kollibri — oui, ces oiseaux aux ailes vives et aux couleurs vives, symboles de liberté, de mouvement et de résistance douce — accompagnés du Père Fouettard (pour rappeler que l’engagement a aussi ses rigueurs) et de Saint-Nicolas (pour rappeler que la joie, la générosité et la solidarité sont des valeurs non négociables), se sont réunis du 05.12.2025 au 07.12.2025 le temps d’un Weekend pour rêver, mais surtout pour co-créé la prochaine édition du Festival Koll an Aktioun.
Dans ce rêve éveillé , car c’est bien de cela qu’il s’agit : un rêve lucide, un projet qui prend racine dans l’imaginaire pour germer dans le concret , nous avons entre autres mis l’accent sur les valeurs que nous souhaitons transmettre : la solidarité, la créativité, la résistance joyeuse, la convivialité engagée, l’écologie culturelle, la place de l’art comme outil de transformation sociale. Et surtout, nous avons réfléchi à la façon de les rendre visibles, palpables, vivantes au milieu de tant d’événements culturels que l’on consomme sans se poser la question : « Quel est le message ? »
Vous vous dites : « Un Visionsweekend ? C’est quoi, ces hippys ? Sûrement un week-end assis autour d’un feu en train de chanter des mantras, et de consommer je ne sais quoi qui fait planer… »
Si c’est le cas, détrompez-vous.
Parce que oui, aujourd’hui, on va à des festivals pour danser, boire, se détendre , et c’est bien. Mais nous, nous croyons qu’un événement culturel peut être bien plus qu’un divertissement ou un bien de consommation. Il peut être un lieu de rencontre, de questionnement, de réveil des consciences, de partage de projets. Il peut être un espace où l’on ne consomme pas seulement de la musique ou des spectacles, mais aussi des idées, des émotions, des solidarités.
Et c’est précisément ce que nous voulons construire : un festival où l’art et l’action se rencontrent, où les artistes ne sont pas seulement des spectacles, mais des catalyseurs de réflexion et d’engagement. Où le public n’est pas seulement un consommateur, mais un acteur. Où chaque scène, chaque atelier, chaque repas, chaque moment de pause, devient une occasion de réfléchir, d’échanger, de créer ensemble.
Si vous souhaitez savoir quel est notre message ce n’est pas un slogan, ce n’est pas une affiche, c’est une expérience à vivre , alors on se donne rendez-vous au plus tard du 22 au 24 mai 2026 à Haut-Martelange.
Car le message, ce n’est pas ce qu’on dit. C’est ce qu’on fait. Et ce qu’on vit. Ensemble.
P.S. : Ce texte n’est pas un appel à la passivité, mais un appel à l’action , joyeuse, collective, créative.
Et si vous êtes là, c’est que vous aussi, vous avez envie de rêver éveillé. Alors, à très vite dans
le réel, pas seulement dans le rêve.
rONDERËM DEN uEWEN
Ronderëm den Uewen is a pretty simple idea - however it seems almost revolutionary. It translates to around the fireplace/stove. And that’s what we do: we meet in our very own stock where we actually put up an ancient stove that not only warms us but also a soup or mulled wine - depending on your needs.
We’d love for people to gather just to spend time together, to get creative together and to talk. About views they share and about opinions that might differ.
To create a space to allow exchange as well as constructive criticism and where different opinions can be shared and discussed. An important value that seems to be less and less common. But you’ll find it at Ronderëm den Uewen! So keep your eyes peeled for any upcoming editions. Sometimes it might also just be dancing around the stove.
