The superb and intensely focused (The New York Times) Quatuor Ébène performs quartets from Beethoven’s early days to a work written near the end of his life. Beethoven’s Op. 18 quartets were written in the shadows of Haydn and Mozart, but in No. 5 he gives us something unique: a quartet simmering with restless energy that only finds relief in its whirling finale. The String Quartet in E-flat Major is quintessential late Beethoven, a daring exploration of the expanse of sound and of new harmonic ground.
