Hans-Peter and Volker Stenzl enable us to experience a historic moment in their live recording from the Ehrbar Saal in Vienna. On two original Ehrbar grand pianos, they play Johannes Brahms' original version of his 4th Symphony, as performed in the eponymous hall for friends of the composer in 1885. This testimony to a fading time is accompanied by another work of irreversible finality, Maurice Ravel's tone poem La Valse. Like no other dance, the waltz, which Ravel shatters to bits and Brahms only hints at in finale, defined the 19th century. A quasi volcanic orchestral dance by one of the best piano duos in the world!
