At the concert I attended, pianists involved in this work across different countries performed a variety of pieces. However, I was left with many questions regarding the quality of the performance, the level of preparation, and the respect shown to the audience in presenting the music in such a way.
Perhaps in the environments where they usually perform, this level is acceptable, and the context itself plays a different role. But when an artist appears on a central concert stage in a city — where there is a strong likelihood of an audience that includes professional musicians — should they not be held to a different standard of preparation?
Or do musicians have the right to perform at the level they have reached, with all forms of artistic expression being equally valid?
