yes there has always been electronic music at the festivals, but obviously never as intense as it is now. There was always a human element with electric guitars and singing etc, but now it's just dancing to a machine.
This would be fine up to a point if
they weren't also punting an 'earth spirit' philosophy.
What no one seems to have noticed is that they have come out to a sacred pagan site to listen to the most artificial music ever made.
I say, we may have been distracted in this direction 20 years ago, but we really should step back and see what we're actually doing.
