Schubert’s late masterpiece for string quartet, his 15th and final quartet in G major D887, was composed in 1826. Although the first movement was performed at a Vienna Musikverein concert devoted to his music, he couldn’t find anyone to publish it.

It displays an almost Beethovenian profundity, and is a dramatic departure from the two previous song-based quartets that had proved popular. The writing is assured and the harmonies audacious. It is a dark, rather introverted work, full of passionate outbursts and drama.

Berg’s Quartet Op.3 was premiered in 1911, towards the end of his studies with Schoenberg. It was badly received and baffled listeners and performers alike. Like the Schubert G major, it displays daring harmonies and a remarkable technical assurance.

This CD is the Kuss Quartet’s debut on Onyx. They are regular performers at the Edinburgh and Salzburg festivals, and also perform regularly in New York, London and their home city of Berlin.
