Back to Bach.
I quite like how "Aus der Tiefe rufe ich" goes seamless to "So du willst" (so much so that I considered them one movement for a long time before finally checking it out and realising my mistake

). My absolute favourite though is "Meine Seele wartet auf den Herrn". I can't describe why, it just captivated me from the start.
This is such a young Bach - there are flashes of his characteristic style in places (particularly the last movement), but he's not yet 'settled in' to the voice he would use for much of his output. But he still manages to convey the emotional impact he's going for.
For the
most typical of his cantatas, I listened to a handful of samples on YT and came up with Harnoncourt's recording of this one. (Normally I'll take Richter's account of these works where available, and his is out there, but his first movement is so very
slow stately as to be painful. I much prefer a choral presentation to 'one-voice-per-part' for this work, which ruled a few other versions out.)
I did come across
an excellent volume presenting an analysis and a number of commentaries on the work at my local Half Price Books some years back and snapped it up, and have read through it twice now.
You
may recognize the center movement.
