Concert Hall in Vienna

Vienna is the home of Strauss and where Mozart did much of his work.  There are classical music concerts all over Vienna every night, with period costumed people aggressively working to sell tickets nearly everywhere.  We planned to see a concert each night, but what we saw the first night was sort of a Strauss-Mozart hit-parade for tourists and we think the other venues would likely be much of the same tunes, so we did not go to any additional concerts.   We did, however, patronize the many street musicians.
