The CAERUS chamber ensemble was founded in Berlin in 2017. It opposes the passing of time by capturing the moment. Inspired by Caerus – in ancient Greece a religious-philosophical term about the right, unique moment of a decision and at the same time personified as a deity in mythology – a unique body of sound was formed from outstanding instrumentalists of the young European generation of musicians on the initiative of violinist Jonian-Ilias Kadesha and cellist Florian Schmidt-Bartha, which allows the spirit of Caerus to flow into its creative process and thereby create unique, unforeseen things: music created from the right, never again reproducible moment. 

As a flexible collective, the CAERUS chamber ensemble plays in programs with various instrumentations – from duos to small chamber orchestras; the design of the programs thus gains the greatest freedom and relevance in terms of content. The young artists – all prize winners of renowned international competitions, such as. Tchaikovsky, Joseph Joachim, Long-Thibaut, Joseph Haydn, Prague Spring, Leopold Mozart and members of leading European orchestras such as the Chamber Orchestra of Europe, the Camerata Bern, the Kammerakadamie Potsdam, the West-Eastern Divan Orchestra, the Chiaroscuro Quartet, the Kelemen Quartet and the Trio Gaspard – are filled with the common desire to perform chamber music at the highest level, because in this each individual is challenged as a soloist and at the same time as a sensitive part of a community; Freedom and responsibility unite in an indispensable pursuit of chamber music excellence. 

After its first steps and projects in its founding year, including concerts at the Bronnbach Music Spring Festival at the Bronnbach Monastery, the ensemble experienced a renaissance in 2020 and has since performed at festivals such as Young Euro Classic at the Konzerthaus Berlin, the Kalamata International Music Days in Greece, Music at Tresanton in Cornwall (UK), the International Schlosskonzerte Meersburg and the Konzerthaus Blaibach. In addition, radio recordings by BR, BBC Radio 3 and Deutschlandfunk Kultur document the artistic work of the ensemble. 

At the festival INS OFFENE…! at the Kühlhaus Berlin, the ensemble can be experienced as a string quartet in a special instrumentation with two cellos, consisting of violist Timothy Ridout, cellist Tim Posner and the two founders of the ensemble, Jonian-Ilias Kadesha and Florian Schmidt-Bartha. 

Jonian Ilias Kadesha, violin

“To regard him simply as a huge talent is not enough: there is an element of pure genius in this young man” – Süddeutsche Zeitung 

Born in Athens of Albanian and Greek heritage, Jonian Ilias Kadesha has a keen interest in philosophy and rhetoric and possesses boundless imagination of sound and curation. His playing is characterized by stylistic accuracy and idiomatic interpretation from early to contemporary works, executed with immaculate articulation.

He has also performed at Kronberg Chamber Music Connects the World and the Verbier Academy Festival. Jonian Ilias Kadesha is a co-founder of the award-winning Trio Gaspard, which regularly performs at festivals and in music centers in Europe as well as the United States. Kadesha, together with cellist Florian Schmidt-Bartha, founded the CAERUS Chamber Ensemble in 2017, a flexible chamber ensemble composed of outstanding instrumentalists of the young European generation of musicians.
