I've seen this show previously as a bootleg DVD [called "The Summit 1975"]. Same footage but cleaned up. But even then, there was only so much that could be done. Video is in 4:3, a times a bit fuzzy and limited number of cameras. In some cases [particularly at the beginning], you will see the band just from the left side - thereby seeing just the side of John's face - when in view. In some cases you will see stills [unsure if missing video, bad video or just by design].
The audio is only in stereo and seems to me it has a bit of an odd sound for the vocals. Sort of like sining through the tube of a roll of paper towels or something.
There are no extras to this release [odd for any release]. Even the bootleg had a pile of extras. :-)
The band is at the top of their game witha 25 track set. Not a bum track in the set. And of course some wacky comments from Keith.
[Judging from the quality, not surprised there is no Blu-ray release.]
