Already at the beginning of their research, the Duo Egri & Pertis discovered that not even the duets or duo works of well-known composers had been fully discovered, not to mention less famous artists (Ignaz Moscheles, Emanuel Chabrier, John Field etc.).
Following this findings, they began to work systematically, supported by musicologists and leading employees of international libraries. They cooperated particularly closely with Schubert researcher Dr. Walburga Litschauer and Liszt researcher Maria Eckhardt.
Over the years, the duo has assembled a collection of more than 6000 pages of sheet music, which they continuously incorporate into their repertoire and which they present in the form of concerts, radio, CD and DVD recordings.
For example, the audience has a chance to get to know the works of Henri Herz, Carl Reinecke, Joseph Joachim, and Josef Dichler. Special moments of the duo’s “discovery work”:
- Premier performance and recording of the Great Concert Piece on Mendelssohn’s “Songs without Words” by Franz Liszt, which the duo reconstructed from the autograph,
- Premier performance and recording of the Grand Duo by Felix Mendelssohn,
- Premier performance and recording of the Concert Piece in F major by Robert Schumann,
- Completion and premier of the original version of Schubert’s Rondo in D major D 608 (with subsequent premier recording).
Performances of works by Onslow, Pleyel, Thalberg, Dohnányi and Rimski-Korsakow caused a sensation as well. Many of the duo’s premier recordings (works by Saint-Saëns, Mendelssohn, Pleyel, Thalberg, Liszt, Massenet, Franck and others) were released by the Hungaroton label.
Another exciting task for Egri & Pertis was the collaboration on the New Schubert Edition of the Bärenreiter-Verlag (scientific-critical edition of all works by Franz Schubert) from 2008. They also participated in the presentation of the volumes (Schubert’s four-handed early and late works). In 2013, one of these literature concerts (four-handed piano works from Schubert’s last year) was published as a live recording in the CD series “Klingende Forschung” (“Sounding Research”) of the Austrian Academy of Sciences.
