Lyrically was played the second movement, before in the final movement his breathtaking virtuosity thrilled the audience. A long applause from the audience rewarded his performance, which was confirmed in encore.

W. A. Mozart - Concerto for Clarinet and Orchestra KV 622
...a young man in tails and a striking white cumberbund walked on the stage to become the conquering hero. Matej Kozub, had only two days to prepare but he gave a brilliant performance. It may be a cliché, but it is true that Matej Kozub held the audience spellbound. Playing his fine clarinet with agility, the music Kozub produced seemed effortless and was utterly beautiful.
