In 2018, the Zemlinsky Quartet founded a chamber music series in Prague called 4plus, where the quartet is being joined by outstanding Czech and foreign musicians to perform many different works from the world of chamber music. One of the two intense motivations was this: since a long time, the Zemlinsky Quartet desired to perform more concerts in Prague, to be able to design its own program of the concerts, and to be able to invite excellent musicians in Prague that it met during its concert performances worldwide. The second idea became real in 2021. In 2007-2014, Zemlinsky Quartet recorded the complete works for string quartet by the most recognized and perhaps most beloved Czech composer, Antonín Dvořák. The ensemble appears to be only the fourth group in history to undertake such a big and demanding project. Since the beginning of this project, the quartet members had a specific idea in mind: to perform this complete cycle in their home city – in Prague. This happened in 2021 within this chamber music series 4plus, as Dvořák had the 180th anniversary of birth that year.

The Zemlinsky Quartet of course continues organizing this chamber music series, as it seems to be successful, and as it brings good music and excellent guest artists to the Prague audience. The main theme of 2023 is Czech-Spanish Dialogues, in other words: Czech-Spanish cooperation on the concert stage. This idea was created long time ago already, but when the Instituto Cervantes, the Spanish cultural organization in Prague, became very much interested in co-organizing such an event, this idea became finally true in 2023. This quite unique idea has one more interesting coincidence – in the second half of 2023, Spain will hold the presidency of the European Union.
