I just read that letter written by Mr. Kremer. I could understand well how he feels. The classical music world needs the conscience, intelligence and courage like his. Thank you for posting!
One thing in it that struck a chord with me was the image thing...particularly the sex appeal aspect of it. I was watching a video on YouTube of a pianist playing a popular piece. I'd never heard of her before (and I can't recall her name), but I gather she is at least somewhat popular. She was very beautiful and dressed in sexually provocative clothing - nothing particularly wrong with that IMO. She played very well, or I might feel differently about it. What I found disturbing is that so many of the comments compared her to Valentina Lisitsa - not her appearance, but her playing. Lisitsa has recorded the same piece, but as pianists they have almost nothing in common (Lisitsa's technique is superior, and IMO the other woman's interpretation was superior). So why not compare her with other interpreters, like Sokolov and Arrau, etc.? So I explained it away in my mind as being a product of the YouTube arena, which is not known for being particularly high-brow, but apparently it's something of a problem in high-brow arenas as well, and truth be told I'm not convinced that's a new thing. Take Franz Liszt, for example. He was a sex god and a crowd-pleaser to boot. No doubt he could be a tasteless musician from time to time, especially in his youth, but he was a virtuoso, arguably unparalleled, so it's hard to say that he built his career on that image (even though I think it probably helped). Sex idols in the piano world are unusual, but the opera has always favored crowd-pleasers, and musicianship has always been but one part of that.
