Since 2012, jazz fans have been celebrating International Jazz Day on April 30th each year. The guiding principle is to “highlight jazz and its diplomatic role in uniting people across the globe.” It’s that time again! We celebrate musical diversity and unity. Chicago is the official host city of this year’s 15th anniversary edition. The day will once again be celebrated worldwide with numerous concerts and educational programmes.
Jazz as a cultural blueprint for the world
Jazz pianist and UNESCO Ambassador Herbie Hancock takes the lead alongside UNESCO Director-General Audrey Azoulay for Jazz Day. In Herbie Hancock’s announcement, he stated, “Given conflicts and divisions in many parts of the world, I hope that this year’s celebration can inspire people of all nations towards healing, hope, and cooperation in promoting peace.”
Annual All-Star Global Concert as the crowning finale
Chicago will host International Jazz Day 2026 in cooperation with the Chicago Jazz Alliance, the Ravinia Festival, the Illinois Arts Council, and various other partners. The finale, as in previous years, will be the online-streamed “All-Star Global Concert,” featuring over two dozen top-tier jazz musicians from around the world. As usual, the line-up will be announced shortly before the event.
Unequivocally diverse: genre without pigeonholes
There is no universally valid definition of jazz, but there is a charming one: it is often described as the music of the moment, especially as the musicians often deviate from the sheet music, improvise, and play what they feel in that instance. As such, improvisation, syncopation, call-and-response elements, and, for the most part, a swinging rhythmic feel are among the most important characteristics of jazz. In addition, jazz celebrates musical innovation and encourages the deliberate breaking of rules. After all, who wants to constrain themselves by thinking in outdated categories? In a sense, jazz always has something experimental about it. From the very beginning, musicians have always embraced new and extravagant ideas. As a result, jazz quickly evolved into a wide variety of multifaceted subgenres.
From New Orleans to joyful diversity
Jazz began around 1915 in New Orleans as a fusion of the blues music of African-American slave labourers in the southern states of the USA and the diverse cultural influences of European immigrants. Various sub-genres subsequently developed, such as Dixieland, Chicago Jazz, and – when bands outside of the black community began to play jazz from the 1930s onwards – swing, which was mostly danceable. From around the 1950s, things became even more confusing and jazz evolved into the wilder bebop, the mellower cool jazz, gypsy swing, Latin jazz, jazz rock, fusion jazz, and many other facets.
Typical instruments in jazz
Jazz is deeply rooted in the idea that the personality of the player should shape the performance of a piece. Every jazz musician strives to develop their own characteristic sound and musical signature. Jazz embraces individuality and diversity, which is why there is no fixed set of instruments. The trumpet, flugelhorn, trombone, saxophone, clarinet, and now also the tuba are some of the most common solo instruments in jazz. The rhythm section is made up of the drum set and the bass – usually in the form of a double or upright bass. Chordal instruments include the guitar, banjo, and especially the piano, all of which can also shine as soloists.
Legendary jazz greats
The range of outstanding jazz musicians is so vast that any attempt to compile a definitive list of the most influential artists is bound to fail. Those not mentioned here may please forgive me. Among the most notable guitarists in the history of jazz are Charlie Christian, Django Reinhardt, and Wes Montgomery, as well as John McLaughlin, Pat Metheny, and Al Di Meola. On the trumpet, there were heroes such as Dizzy Gillespie (the man with the “bent trumpet”), the innovative genius Miles Davis, and, of course, Louis “Satchmo” Armstrong and the virtuoso Chet Baker. Pianist Count Basie was known as the “Count of Swing” and pioneered the comping technique. And Jazz Day organiser Herbie Hancock is a true icon of modern jazz. Let’s not forget Charlie Parker on the saxophone, Ella Fitzgerald with her brilliant voice, and many more. There are so many who deserve to be admired.
Wolfgang Hafner
The German jazz drummer Wolfgang Hafner is the most popular drumming bandleader in European jazz. He can look back on an extraordinary career that extends far beyond jazz. His facial expressions and body language convey the joy of the music and the rhythm. He is the epitome of someone who cherishes what he does – and thousands of music fans around the world get to enjoy the result. He has released more than ten albums under his own name, the latest of which, ‘Kind of Cool’, received the German Jazz Gold Award.
Max Treutner
For the saxophonist, composer, and improviser Max Treutner, born in the Stuttgart area in 1998, the Zen Garden is his personal sanctuary where he can find himself. And this is precisely what he has captured on his eponymous album. Does music need a place where it can emerge and unfold, or does it itself shape the landscape within which it finds its place? Max Treutner clearly leans towards the second assumption.
Lutz Häfner
It has long been no secret that saxophonist Lutz Häfner ranks among the very best in his field. The press hails him as an ‘exceptional musician’, one of Germany’s ‘best saxophonists’ (NN), and writes of his ‘world-class status’. This is an artist who knows how to transport his audience far away into undiscovered worlds of sound and challenge them with unusual interpretations. At the same time, his playing is characterised by a harmonious, profound lyricism and striking ornamentation. On International Jazz Day, he will be performing as part of a double concert at the Jazzklub Krefeld.
Jakob Manz
Among others, Jakob Manz is currently touring with The Jakob Manz Project, a group that ranks among the most successful bands in the young German jazz scene. Hardly any other young group elicits such rapturous enthusiasm from its audience. Whether in a club or on a major festival stage, the band’s inescapable energy reaches every corner of the venue, drawing the audience into their multi-layered music.
Stephanie Lottermoser – saxophonist
When Stephanie Lottermoser and her band fill the hall with a fine blend of soul, pop, and jazz, time and space become irrelevant. All that matters then is the sound and the stage presence of the singer and saxophonist. The fact that she now performs worldwide is down to her unique sound, with which she has carved out a place for herself in the global jazz cosmos. Stephanie Lottermoser will celebrate International Jazz Day 2026 with her quartet on stage at the NICA Jazz Club in Hamburg.
Gordon L. Goodwin
The American Gordon L. Goodwin – a renowned saxophonist and pianist known, among other things, as the bandleader of the Big Phat Band – is sadly no longer with us. He passed away on 8 December at the age of 70. Given the indelible mark he has left on the genre, others will surely keep his legacy alive in their performances.
Good vibes
Last, but not least, we shouldn’t forget the vibraphonists. After all, there is no genre in which this instrument is more popular than in jazz. The first person to introduce the vibraphone was Red Norvo. Then came Lionel Hampton (the personification of a musical volcano) and Milt Jackson, who adapted Charlie Parker’s innovations to the instrument.

Plenty of fresh talent
The fact that there is no shortage of new talent in jazz is proof of its diversity. It remains to be seen who will inspire us on Global Jazz Day 2026, especially as the worldwide line-up has not yet been officially announced. After all, there are an extraordinary number of newcomers, many of whom cross genre boundaries with ease. Let’s take a look at a few examples that can hardly be called ‘newcomers’ anymore:
Jazzrausch Bigband
On International Jazz Day, the Jazzrausch Bigband will be playing at the Bergson Kunstkraftwerk, which has been the new home of the 20-piece ensemble since 2024. Currently one of the hottest acts on the scene, these boundary-pushers do not limit themselves to straight-up jazz, but instead incorporate elements of pop, fusion, rap, and more into their molten fusion of big band sound.
Christian Elsässer
Size Matters. Few musicians in Europe are as adept at working with large ensembles as Christian Elsässer. It is incredible what textures, timbres, details, and forms the Munich-based musician draws out of these lavishly staffed formations. He has already composed and arranged for the Dutch Metropole Orkest, the Scottish National Jazz Orchestra, and all the German radio big bands. And his own Christian Elsässer Jazz Orchestra has long been an institution on the scene.
Dirty Loops
Dirty Loops was formed by three music students from Stockholm. Initially, the band made a name for themselves with their idiosyncratic, boundary-pushing cover versions. Their sound lies somewhere between jazz, funk, fusion, electronica, and pop – genres that couldn’t be further apart. “The reason for starting the band was simply to have fun and a creative outlet,” said bassist Henrik Linder, who has been working as a session musician since the age of 16.
Snarky Puppy
The US-based collective of musicians specialising in fusion and jazz-rock has already bagged five Grammys since its formation in 2004. To call them “up-and-coming” would not begin to do justice to their stature. Made up of over 25 musicians, the band combines intense grooves with high musical intelligence, much to the delight of the audience.
