Wiener Blut (Viennese Blood/Viennese Spirit) op. 354 is a waltz by Strauss II, first performed in 1873. Originally created to celebrate the wedding of the Emperor Franz Josef's daughter Archduchess Gisela Louise Maria to Prince Leopold of Bavaria. However, the waltz was also chiefly noted by Strauss' biographers as the début of Strauss with the world-renowned Vienna Philharmonic Orchestra. For many years, the Philharmonic had dismissed any association with the 'Waltz King' as it had not wished to be related to his light music.
