I am not sure what Johannes Brahms would have said, but I think Franz Schubert would have warmed up to the idea, especially after a few beers at the “Schwarze Katze”, one of his favourite pubs in Vienna: blending blues with the second movement of his String Quintet in C (D.956) and the second movement of Brahms’ String Sextett No. 1. In the realm of emotions, blues and Romantic classical music are immediate neighbours. Both express mankind’s longing for a better world, both oscillate between joy and sadness, both find their expression most of the time in plaintive ballads. So marrying the two can be an interesting experiment. And Schubert was open-minded person, enjoying performing in a small circle of like-minded musicians.
