PART 1: Aus der Tiefen rufe ich...: moments from mvts. 1-2

For our thirtieth(!) episode, we celebrate by taking a five-movement cantata and giving you one moment from each. This will be a two-part series; this episode introduces the cantata and delves into Christian's moments from the first two movements, while next week we'll see his moments for movements 3-5.  This very early work uses arcane sounds and woeful harmonies to call "out of the depths," but it also contains minute-for-minute some of the most varied experiments in voice-leading, rhythm, suspended harmonies, beat units, and final chord progressions (cadences) that Bach ever wrote. Are they attempts at an older style, or are they strangely new?  https://www.youtube.com/watch?v=TMWDxIkl1fc
