Vienna Boys Choir

I got ticket information through the Vienna Boys' Choir website two years ago: http://www.wsk.at/jart/prj3/wsk_website/main.jart?rel=en&content-id=1180694117867&reserve-mode=active I recall having to place my order by phone. Availability is generally quite limited and tickets should be ordered well in advance to avoid disappointment. Concerts are often done during Advent mass at the Hofmusikkapelle (a chapel within the Hofpurg Palace). The choir performs from the choir loft during mass and can't really be seen. They come down at the end of mass for 1-2 songs. I hope that this helps.
