Salzburg, the sleepy provincial city where Mozart’s father was a court violinist and Kapellmeister in the 1740-60s, was in the previous century home to two influential composers in their own right—Heinrich Ignaz Franz von Biber and Georg Muffat. Biber, regarded as one of the greatest violinists of his time, worked for most of his life in the Salzburg court and developed groundbreaking techniques in string writing. Muffat also worked as a court musician in Salzburg for ten years during his cosmopolitan career. The Sebastians top off this program with their signature rendition of the Follia by Antonio Vivaldi, who settled in Vienna in his final years. The centerpiece of this varied program is Mozart’s Concerto in A, K. 414, which will be performed by Yi-heng Yang on a fortepiano built in the style of Mozart’s own instrument, recreating the incisive and dramatic sounds of his musical language. Not only does the stylistic juxtaposition of Mozart with his Baroque predecessors cast the beloved Classical genius in an arresting new light, but the combined collection of composers becomes a fantastical historical journey through two of Europe’s most musical cities.
