We all know the list that GB posted here on the zone way ago about the concerts that are in the vault.
Which concerts that aren't released are suitable for a great release videowise?
So, which concert does QP actually has the single camera feeds from? So NOT the edited videomix.
It looks like more tapes have been found sunce then. Or, the archivist has been granted acces to more recordings (Brian's soundboard collection).
They obviously have some US 1977 NOTW concerts. They used Sleeping on the sidewalk from those show (s).
And with the new box we also got confirmation they have LA 22-12-77.
Sadly those recordings are regarded as not good enough for official release (or so it seems at least).
Not good enough for official release just mean QP don't want to release (interesting) live material. The broadcast sessions are a great example of three recordings that could has been great stand alone live albums becoming edited bits of concerts.
The other thing to consider is that it could be the record company who want to sit on these recordings for later release (probably too late)
