We recently discovered (by the folks on this forum) that the Vienna opera and boys' choir is off in July/August. There are other "opera" options in Vienna at that time, which look pretty touristy. Is there one that you all recommend above the rest? We are in Vienna August 6 and 7, so this is the list I'm looking at: https://www.vienna-concert.com/events-month-page/en/7/08-2016/7/Classical-Concerts-Vienna-.html
Do you all recommend one over the other? Thanks in advance!
