The only logic I could bring in is that a lot of people into that type of music are no longer able to go out - ie if they've got kids - but are still into that sound. In which case it seems to make sense.
The generational shift we need to get ready for is when people who grew up in the 90s reach their 40s. That's not very far away.
Or they're too young and this is a way of giving a taste of what clublife is like?
