The movie has two main parts, one is a live concert and the other one is some Discovey videos. The live concert has awful sound, mixed in DD2.0, my center speaker sounded as it was damaged. When I switched to stereo, it was a little bit better. The videos are much better. The sound is much clearer, although this is not what I would call a "reference" disc.
If youre a big ELO fan, you should buy it. Otherwise stay away.
