Hi,
This has been in the works for almost 10 years, and in the past 5, the Zappa board has been unreal in demanding this.
The main issues, appear to be that all the sound was not in sync with any of the visuals and this made things very tricky. That means, they have to pull the music apart and then sync one item ... oooppps, that part can't be right, and keep adjusting things until they get it reasonably right so only audio experts could see the difference and the problems with it.
The album, yes, is magnificent, and in my book FZ at his best ... and should help establish FZ as a master musician in the American landscape of music, that is not interested in musicians, only stars. He deserves this, and in my book, this is Gail's gift to us all before part'ing from us. She fought tooth and nail and put up with so much poop about this, it isn't funny, but she would not give up on the quality she wanted ... and she will win in the end. She stood up for what was right, and not sloppy!
It should be the album of the year. and pull off awards left and right.
