Joseph Haas (1879-1960) was a German composer and student of Max Reger, whose works for violin and piano (1905-1912) clearly show the development from an early style strongly influenced by Reger to greater independence. While the early sonatinas are still strictly formal and harmonically dense, his personal style is already evident in the Violin Sonata, Op. 21. With the Suite Grillen, Op. 40, he achieves a mature, transparent style of writing in which the piano and violin interact on an equal footing. The Czech violinist Ludmila Pavlova has been concertmaster of the Prague Chamber Orchestra since 2023 and teaches at the Academy of Performing Arts in Prague. Alissa Firsova is a pianist, composer, and conductor. Her works are performed internationally, and she also performs regularly as a soloist and chamber musician. Pavlova and Firsova have been working together as a duo since 2017 and present their debut recording here!
