If complaints are made as to excessive sound (noise to some!) levels I would say GOOD.
We need more complaints especially about excessive sound levels at dance and ceilidh venues where the music is so loud that even young dancers complain and routinely use earplugs - which compromises the sound quality. I suffered all of some ceilidhs at Towersey using earplugs - the dancing was good and not to be missed but the event could have been so much more enjoyable for the majority of dancers if the sound had simply been turned down. Folk festival organisers take note!
