The Kosztolánszki Quintet is a vibrant young group, playing modern jazz, based on the musical world of the sixties and seventies, inspired by their own individual musical culture and experiences. Their declared purpose is to open a window and give the younger generation an insight into their musical diversity, which, in addition to their originals, creates a rolling atmosphere through the compositions and styles of hard-bop musicians. The band is proud that, although the jazz genre is hardly the most popular among young people, they have managed to win a secure, inclusive and growing audience for their concerts.

In addition to the 19-year-old tenor saxophonist and leader, Dominik Kosztolánszki, the Young Jazz Musician of the Year prize-holder drummer Ambrus Richter, the metronome of the quintet, and the three other young and talented musicians have also performed at numerous local and foreign club concerts already.
