I'm afraid I won't be joining you as I'm from the Netherlands.
That would be an expensive trip
We have here the 'pinkpop classic' festival, which is meant for older bands. But I think it's a bit too mainstream for me. They are thinking of creating a new festival at the location where the Lowlands festival (to which I go every year) is held. The idea is to make it like Lowlands, so with a lot of atmosphere and culture next to the music, but mainly focused on older bands. Could be very interesting, but there's not much information available on that festival yet...
