The biggest part is announced of the line-up of the 538 Queensdayfestival at the Museumsquare in Amsterdam. Amongst others Armin van Buuren, Sander van Doorn and Sidney Samson are present on Saturday the 30th of April between 12:00 and 21:00 CET. This year Armin van Buuren will close the event!

Koninginnedag (Queensday) is always a highlight of the year in Amsterdam. Not neccesarily for trance, but certainly for the massive parties everywhere in the streets in the whole center. Every year about 500,000 people from outside Amsterdam visit the night before and about 1,000,000 people on the day itself. There are a few places with big stages and famous (Dutch) artists, but there are unknown DJ's playing about everywhere you can imagine. Every street (or canal) has at least one DJ booth and sometimes even 3 or 4. I'm coming there now for over 15 years and I haven't missed a single time. There's only one thing: you mustn't stay sober hahaha.
