By comparison though Azza, whilst the scene in Europe and further a field for that matter, is healthy and growing it is small by comparison to the UK. The amount of venues in the UK alone on any given weekend is probably more than the rest of the work put together, there's probably more venues in the North West than Europe on any weekend
You are right though the scene in the Uk will change. Whilst there are more youngsters than say five years ago, there still aren't enough to replace the mass exodus that will happen given the average age of allnighter and indeed soul night attendees. The average age has to be in the 50s, I have little enthusiasm at the minute for nighters, mainly because of my job, 60-70 hours per week and away all week, and the recovery time. I cannot be alone in that regard. The large majority at any venue are getting on and they will leave the scene one way or another in the next ten years. I doubt there are enough or will be enough to replace them but that won't be a bad thing.
Hopefully the commercialsim will recede and the divs with it. But far too many youngsters seem to be going down the oldies route, not sure if that is to get on the DJ bandwagon or if that is their preferred taste but hopefully that will change otherwise it will be as stale as it is now.
But in reality no one knows how the scene will look, will the youngsters still be as dedicated and hard core when they have bills, mortgages and have to hold a job down...not to mention kids?
P.S. i don't really care how it will look, it is up to those who will keep it going to define how it will be at the end of the day. I doubt anyone really cared 30 or 40 years ago, we were just youngsters living the life, I doubt any of us thought it would still be thriving today.
