Thanks - yes I'm aware of most of those (my handle here is a northern soul record) and do attend but they are relatively niche and I resent the current way mainstream dance music events are presented to the world as something that seems counter to the notion.
Btw I've seen great dancers who barely move their feet; my concern is with the culture where individual expression is subordinated to the cult of commune and the DJ.
As others here have pointed out that is partly down to the promoters packing in as many people as they can; I think control moving over the years from love of the form to strictly commerce has caused a significant change in culture.
