For 30 years, Kaunas Big Band (chief conductor Jievaras Jasinskis) has been the flagman of jazz culture of Kaunas. During the time of activity, the big band has been a witness, participant and creator of the significant jazz events in the country. Kaunas Big Band was the only municipal jazz orchestra for a long time. For a few generations, it has become the life school of jazz for many musicians.

Almost all Lithuanian jazz musicians had some precious moments on stage with Kaunas Big Band : Petras Vyšniauskas, Valerijus Ramoška, Vytautas Labutis, Saulius Šiaučiulis, Arvydas Jofė, Olegas Molokojedovas, Eugenijus Kanevičius, Arkadijus Gotesmanas, Pavelas Giunteris, Vytautas Mikeliūnas, Vytautas Grubliauskas, Liudas Mockūnas, Neda Malūnavičiūtė and others.

It is hard to imagine annual Lithuanian jazz festivals— “Kaunas Jazz”, “Klaipėda Castle Jazz Festival”, “Šiauliai Big Band Festival”—without Kaunas Big Band. The orchestra has been playing at Birštonas Festival since its establishment. All these stages had witnessed many memorable concerts : the audience was introduced to many worldwide known artists, such as Jukka Linkola, Eero Koivistoinen (Finland), Barbara Dennerlein (Germany), Daniel Messina (Argentina), Frank Mantooth, Randy Brecker, Jiggs Whigham (USA), Arkady Shilkloper (Russia), Henk Meutgeert (Holland), Richard Galliano (France), Lasse Lindgren (Sweden), Bob Mintzer (USA), Hermine Deurloo (the Netherlands), Gunhild Carling (Sweden), Peter Beets (the Netherlands), Line Kruse (Denmark) and many more. Together with these artists, Kaunas Big Band played in Poland, Finland, Sweden, Norway, Belarus, Poland, Russia.

Kaunas Big Band had an enormous spectrum of different musical projects. Many of them, like "The Jazz Club of Konradas", "Drum Show", "From Jazz to Blues", "C+M+B JAZZ (Jazz of Three Kings)", "Jazz and Breakdance show", "Samba Del Gringo", "Dance! Jazz!" were prepared with the longtime leader of the Big Band, Romualdas Grabštas.

Kaunas Big Band has performed in prestigious concert halls and arenas, available to host a few thousand people. Highest quality jazz professionals, Estrada and pop musicians have been invited as soloists alongside Kaunas Big Band. The orchestra's most significant ambition has always been to spread professionalism and Jazz music rather than pursuing the sensations. This was tirelessly instilled by one of its creators Romualdas Grabštas (1943 - 2009). Such direction was followed by other conductors: Skirmantas Sasnauskas, Tomas Botyrius, Petras Tadaras, Liutauras Janušaitis, and the current chief conductor Jievaras Jasinskis.

Kaunas Big Band is in particular loyal for the youngest listeners. The concert cycle of “Jazz lessons” as well as interactive musical adventure “Džiazolendas” confidently nurture the new generation. They willingly join the excursions through different roads and paths of jazz.
