The Krisztián Oláh Quartet is the young pianist-composer's most important musical project, which can also be felt through the atmosphere created by the four musicians. The band's repertoire is based on Krisztián's own compositions, but all the members are also great improvisers, so spontaneous and collective improvisation is an integral part of their performances, embodying the spirit and musical tools of today, thus forming a fresh and complex sound world for the band.

Multi-award-winner pianist and composer Krisztián Oláh came third at the Montreux Jazz Festival at the age of 20, and in 2018, he was the first Hungarian jazz pianist to reach the finals of the international piano competition organized by the Thelonious Monk Institute. Classical music elements and compositional techniques, as well as the improvisational flow and abstract rhythms of contemporary jazz, form an important part of his music. He aims to connect and synthesize these two musical worlds organically, creating a dynamic, vibrant contemporary musical world.
