it seems to me that there are two very different things here.
Clearly for some people 'doing the Proms' is a friendly, very much community experience - the delight in the hours of various queueing, the camaraderie, the inner sanctum knowledge, the sharing, the traditions, ------ and then - there is the musical experience where I as person X experience a performance of a work by composer Y given by performers Z.
It seems to me that the first experience is much more of a religious/sociologically interesting cult matter than a musical one. It clearly also provides lots of the dopamines that some of its followers crave: it is one that (having experienced it several times) I find a complete 'turn off'...
Whereas the 'musical experience' can, of course, be wonderful. Best experienced at home on a good radio. Hence the need for BETTER RECORDED SOUND!!!!!!!!!
