The three musicians Arthur Grumiaux, Georges Janzer and Eve Czako met on June 8, 1966 at Schwetzingen Castle. The result was a memorable concert from the Belgian-Hungarian Grumiaux Trio. The Belgian violinist Arthur Grumiaux and his two chamber music partners selected one of Beethoven's String Trios, Op.9 and the extensive E flat Major Divertimento by Wolfgang Amadeus Mozart. However, instead of a third trio, the ensemble selected a duo for violin and viola by Mozart.

A native of the Belgian Villers-Perwin, Arthur Grumiaux (1921-1986) was the authoritative personality of this trio. As one of the leading (and last) representatives of the Franco-Belgian violin school (Eugène Ysaye and Henri Vieuxtemps were the founders), Grumiaux was a highly regarded soloist and chamber musician. Together with violist Georges Janzer - a member of the famous Hungarian Végh Quartet - and his wife, the Hungarian cellist Eva Czako, Arthur Grumiaux has drawn together a flexible and sinuous chamber music Trinity.

In this concert, the thematic and motivic characteristics of all the musical voices are vividly present; the lively, tuneful, flowery, and sometimes elegiac trajectories of Beethoven’s G Major trio unfolds and blossoms, the voices forming an organic network of melodic veins in which the music pulses and flows, pausing only briefly to lapse into a reverie. Mozart's String Trio K563 was no doubt Beethoven’s model, and triumphs with the light transparency of its dancing and singing figures.

In a word, this a most memorable concert that will welcome repeated listening.
