Barnabás joined the ensemble in the summer of 2022, and it is not enough that he is Sára's younger brother, but by the time it was discussed that he would be a member of Jazzation, he had already completed his jazz studies at the Béla Bartók Conservatory of Music, and had just been admitted to the Liszt Ferenc University of Music for his jazz studies. His dedication to jazz and his singing career is at least as great as his hard work and persistence, thanks to which he learned a whole concert repertoire in a few weeks - as perfectly if he had always sung with us.
