Over the span of two centuries, the Bach family produced more than 50 musicians and composers. On Friday's Performance Today, we have music by Bach -- but not the guy who immediately comes to mind when you hear that name. We'll travel to Denmark to hear an overture by Johann Bernhard Bach, Johann Sebastian Bach's lesser-known second cousin.
