As I said we were camped not far away in the first row & for the most part the session itself and the noise level from it did not appear to be causing a problem.

The points I would raise, because they are ones that may be able to be addressed & improved are
1) There was some disruptive/unwelcome noise but it was not coming from inside the session it eas being made by those outside who were so intent on enjoying themselves that they were not being considerate of others.
2) one of the security guards (for whatever reason, lack of training/ fear/ officiousness) tried to be a bit heavy handed.

In both issues some thing that may help is to review the information for festival goers emphasising the need to have consideration for other and keep noise made outside to a minimum and to tailor the briefing & training for the secuity guards to ensure the low key approach needed..

That said I'm not a festival organiser, and they do work very hard to enable the event to run as smooth as poss. & often they only hear the complaints because the punters don't notice when things work.
