I give this a 10 because it really doesn't get much better if you're even remotely a Zappa fan. The packaging is very nicely done. Every single moment on this box is a joy to hear, but I particularly enjoyed the demos that he did with George Duke. Those are amazing, especially the proto version of "Uncle Remus". The 5.1 mix on both albums is incredible. Finally Zappa's "orchestral cacophony" is heard in all its brilliance with nice separation of the multitude of instruments that appear, particularly on Grand Wazoo, my favorite of the two albums. Gone is this wall of sound that has no layering, as was the case with previous versions. There have been complaints that you have to turn up the volume on the blu ray to properly hear everything, all the details. And ...? I don't see this as a big problem. Someone went as far as to claim that the blu ray disc is defective. This is simply not the case. There was another claim that the center channel is distorted. I think this listener is confusing speaker distortion with that of George Duke's keyboard, which is distorted in various songs for effect. It is not a defect just like there is no defect with the blu ray. I think the surround mixes are very very good, a 9. The sound quality (even on the CDs) is exceptional, crazy to think after 50 years. Don't forget to check out the stereo mixes as well. They blow away previous CD versions. I don't have a setup for Atmos, so I can't make any claims there. Overall a really nice box set with a lot of unreleased material, excellent surround mixes, all in a compact box with Frank's face on it. For the plethora of insanely brilliant outtakes, I land on a 10.
