I was intrigued, so I looked the soloist up on YouTube and found this person (I'm not giving away gender) to be one of the most tasteless musicians I have ever heard. I could even venture to say that s/he is the most tasteless musician alive today, but because I limit my exposure to such players, I am (thankfully) not in a position to make such judgements.
It really bothers me that conductors feel the need to sell concerts the way some people sell cars. It also bothers me that the people new to "classical music" who buy the hype and go to the concert will echo the sentiments of the sales pitch even if the playing has left a bad taste in their collective mouths.
This kind of publicity shows a lack of respect to listeners, and I believe it ultimately thwarts the greater efforts of musicians who devote their lives to trying to play tastefully.
I do know that the city where this conductor conducts has a lively set of musical offerings, and some of them come from tasteful musicians. I hope that fewer and fewer of them buy the
