Documentary captures the unifying power of Bach's music

It's said that music transcends time, and few things illustrate this more than the timeless music of German composer Johann Sebastian Bach.

Though he was born over 300 years ago, to this day, Bach is considered one of the greatest composers of all time and every year in June, the city of Leipzig, Germany – where Bach served as the Thomaskantor, or director of church music in Leipzig, until his death in 1750 – welcomes Bach enthusiasts from all over the world to perform his music at the Bach Festival.
