Rather, I believe that it is very good, if, with the aid of his songs, we can be reminded, among other things, of the social conditions under which Schubert had to work.
Particularly at around the age of 70 you reach a stage where you have to be very careful. If, at that point, you abandon the work you have been doing, there is a good chance that you will just collapse and drift.
Unfortunately, it happens all too seldom that you really disappear behind a work, that you are no longer audible as an interpreter.
Admittedly, it is really our duty, as artists, to hold up a mirror to our own era; but, on the other hand, these works have lives of their own, and they're still alive today.
Which is why, in my lieder concerts, I always strove, when possible, to sing only the works of a single composer, so that the audience could be gradually drawn into a particular creative genius' way of thinking, and could follow him.
