Nun komm, der Heiden Heiland (BWV 61): bass recitative

In our second episode, Christian introduces the royal processional of the cantata Nun komm, der Heiden Heiland. We celebrate the launch of the podcast with this cantata for the new church year, an early Bach work. But the "moment" is hidden later on, where the young Bach uses an experimental sound: a knock at the door from plucked strings with an unresolved harmony. The voice of Jesus sings "Behold, I stand at the door and knock." BWV 61 bass recitative: https://youtu.be/MzWJsRjanC4?t=571
