Silvie (violin) and Dominika (cello) are two of the foremost musical personalities of their generation, and during their studies and early concert careers they were fortunate to meet extraordinary artists and ensembles such as M. Rostropovich, I. Oistrach, P. Schreier, S. Stucky, Amadeus Quartet, Jerusalem Quartet and other world music personalities who influenced their further musical development.

Their common interest in the history of the first half of the 20th century is reflected in the selection of compositions they present to their listeners.

In addition to their core works for string duo, they also focus on works by composers of Jewish descent who were victims of the Holocaust, which is why they named their duo after the composer Gideon Klein.
