The mcrJAZZ Event Series
Three cities, three exceptional evenings and one simple idea: bringing people together to enjoy outstanding live music in carefully selected venues, each with its own distinctive character. The 2026 edition of mcrJAZZ is underway – a series of events that brings us together with our business partners in an atmosphere far removed from everyday conversations about projects and technologies.
For years, mcrJAZZ has brought together live music and the art of building lasting relationships. Each edition offers an opportunity to step away from the routines of everyday business, meet in a more informal setting and share a memorable experience.
After all, while projects, challenges and common business goals bring us together professionally, we believe that lasting partnerships are built, above all, by people.
mcrJAZZ 2026 – Three Cities, One Musical Journey
This year, mcrJAZZ takes us to Gdańsk, Warsaw and Kraków. Each event is hosted in a carefully selected venue whose unique character becomes an integral part of the experience.
At the heart of this year’s musical programme is Mela Koteluk, an artist known for her distinctive voice, sensitivity and remarkable ability to create an intimate atmosphere through live performance.
The evenings are hosted by Tomasz Kammel, who guides our guests through this musical journey.
This year’s edition also marks an important chapter in the event’s history. For the first time, following the changes to the business structure of the former “MERCOR” S.A., mcrJAZZ is jointly hosted by mcr S.A. and MERCOR Light & Vent sp. z o.o.
This collaboration reflects the strong partnership between the two companies. Despite the organisational and business changes, they remain united by a shared commitment to nurturing valuable relationships with their partners.

Gdańsk Behind Us. Warsaw Next!
The opening evening of this year’s edition took place on 17 September 2026 at Stary Maneż in Gdańsk.
It was an evening of live music, meaningful encounters and conversations that we do not always have enough time for in our everyday professional lives. We would like to thank all our guests for joining us and sharing this special occasion.
The second event in the series was scheduled for 15 October 2026 in Warsaw, at the historic Reduta Banku Polskiego, 10 Bielańska Street.
With Mela Koteluk taking to the stage, the venue’s remarkable interiors provide the setting for another evening of music, conversation and shared experiences.
We look forward to more memorable encounters and musical moments as the mcrJAZZ journey continues.
The Grand Finale in Wieliczka
This year’s series will conclude on 19 November 2026 at the Wieliczka Salt Mine.
With its extraordinary setting and unique atmosphere, the venue promises a memorable backdrop for our final gathering. It will be the last opportunity this year to come together with our partners and experience the special atmosphere of mcrJAZZ through live music.
Great music. Great people. Exceptional places.
These are the elements that have shaped the spirit of mcrJAZZ for years.
