Dear Laine,
We are really sorry you did not get the concert experience you were expecting. However, we have to point out that the option you chose for your concert was "Giant Organ Concert", thus it contained organ music. When booking the description read "Giant Organ Concerts".
The pictures we advertise with depict the different kinds of concert experiences you can have with us. When you book an organ concert, eg the picture of a violinist is not applicable. Since we offer very different concerts, not every photo can depict the concert you want to see. This is also due to the system limitations by viator, which does not let you change the photos depending on the concert date.
We still hope you had a pleasant stay in Vienna and maybe see you next time at a violin concert in St. Stephen's.
All the best,
The Team von Concerts in St. Stephen's
