I had always a feeling that M is just captivated by the new age engines ... and what one or another can do and produce. Some of course have good impact and well .. some don't. She wants to explore and she's allowed to do so -- but like we know it doesn't work on live shows very much but end result still for me (personally) is enough (it is what it is) --- at least we get official release (what makes less urge for getting official release). But yeah ... when I always watch DWT, I always wonder why she changed all of that for what we get now --- IMO that "DVD" has a great "vocal use" not so heavy auto-tune/dubbed re-recorded vocals feel.... and YES more alive band, than what we see and hear now
This is just my POV ...
