So far 2013 has been a huge year for Armin van Buuren. Just a few short weeks after finishing up his ASOT 600 tour Armin will be headed to his home city of Leiden, Netherlands for a vey special celebration. The royal family has invited Armin to attend the crowning of Prince Willem-Alexander on April 30, Queensday. Armin is already slated to play a massive free concert in honor of the monumental event. The Dutch have the day off for Queensday and will be out in full force (and covered in orange, of course) for this free concert in Leiden that includes Armin van Buuren, Sunnery James and Ryan Marciano, Jochen Miller, Randy Collé and Dabruck & Klein. Armin was named an Officer in the Order of Orange-Nassau by Queen Beatrix of The Netherlands after performing in Leiden in 2011 so needless to say his performance this year will be something truly special.
