"A world premiere recording! In the course of our research for the five-part CD production 'Beethoven's World 1799-1851' (2020), the Casal Quartet came across not only Carl Czerny, one of Beethoven's two pupils, represented by his 28th String Quartet in A flat major, but also the Viennese composer Anton Eberl (1765-1807), who was Mozart's friend and pupil. As an outstanding pianist and composer, he achieved great popularity and, after returning to Vienna from St. Petersburg, had even more prominent supporters than Beethoven. His life ended unexpectedly at the zenith of his success in 1807. His music, as can be seen in the excellent recordings of the symphonies by Concerto Köln and the piano sonatas by Luca Quintavalle, is often surprisingly modern for its time. Like Mozart's late works and those of the new Beethoven, they augur the revolutionary dawn of Romanticism."
