And of course the Oper!!!!
Tickets can be difficult to get at times, but it is well worth the effort to attend. BTW, standing room is so civilized too. One waits online for these tickets
to go on sale on the day of the performance, and it is easy to get into conversations with others waiting. In fact if you need to leave to grab a bit to eat people will hold your place on line. Once you get into the standing room area (directly below the Royal box) there are rails to lean on and you hold your spot by tying a scarf. Very civilized, at least it was a while back.
And this is the 150th anniversary of Mahler's birth and 100th anniversary of his death. As director of the Vienna Opera, his name is indelible with the Opera legacy.
