Today Armin van Buuren announced that the April 17, 2014 Chicago date on his "Armin Only" tour had to be canceled due to the death of his father-in-law, who reportedly passed away after a long battle with cancer. There will be refunds for this show, but it looks like the April 19 show in Toronto will still be going on as planned. Here is the official statement from his website:

Due to the recent passing of Armin van Buuren’s father-in-law after a lengthy battle with cancer, ALDA Events (the producer of Armin Only) and Live Nation regretfully announce that the show set to take place this Thursday, April 17th at United Center has been cancelled. Everything has been done to try and avoid this cancellation, however due to several factors this is not going to be possible. While Armin feels terrible about the cancellation, it is crucial for him to be with family this week leading up to the funeral this Friday.

ALDA Events, Live Nation, Armada Music and David Lewis Productions would like to express their sincere condolences to the family, and request that the privacy of the family be respected during this incredibly difficult time.

Refunds for the April 17th show are available at the point of purchase. The Armin Only tour will resume Saturday, April 19th in Toronto as planned.

The staff at DAD sends our condolences to Armin, his wife, and their family during their time of loss.
