During the past century, classical music has explored many new and far-flung territories. But it would be a mistake not to recognize the profound influence of earlier music – in particular, that of Bach.

This influence has been felt in many ways. One significant development has been the emergence of historical performance: using centuries-old instruments. The first selection on our podcast, comes from this tradition: the Baroque orchestra Rebel performing an aria from Bach’s St. John Passion, with tenor Rufus Mueller. The historical instruments lend a brightness and transparency that is quite unique.

We’ll then go to a modern performance of an historic work: the chamber orchestra A Far Cry playing Bach’s third Brandenburg Concerto. They bring a unique perspective to the music of Bach, playing it on modern instruments.

Finally, we arrive at the most modern work of the bunch: contemporary composer David Ludwig’s Aria Fantasy for Piano Quartet. It takes some careful listening to hear, but the piece is actually based on Bach’s famous Goldberg Variations; you may hear quotes from the various movements creep in throughout the work.
