Violinists Đana Kahriman, Eva Šulić and Šimun Končić with cellist Pavle Zajcev had their first performance as a string chamber ensemble, under the name kvARTet, last night 3 August in the Rector’s Palace atrium. Their debut was triumphant, judging by the delight of the audience who enjoyed the evening’s excellent repertoire of Beethoven and Dvořák string quartets.
