Ronny, you can’t ask questions like this. Janine Jansen is from an assemblage today young violinist that all create a lot of buzz and they all have very impressive playing techniques. (When I said “young violinist” I mean “not dead yet”). Unfortunately nowadays it is enough to make media buzz, sell CDs and book concerts hall. Still, they all can play. HOW they play from the perspective of interpretive originally is totally different subject. Most of them very average in team of personally of play and have very little to say despite the tremendous technical capacity to speak. Saying that I have to admit the many of them at different events threw very good performances, as some of them phenomenal performances. The whole point to attend a live concert that you never know what happen.
Generally if a soloist was able to book a decent orchestra and decent concern hall then it is more or less assurance that she/he has a rudimental familiarity with the music and the instrument. Everything further is up to you listening intercourse. Look who is conducting and what the orchestra. Look what the program for the concert and if you have any personal interest in the music played. If you do not know the girls then read a few of her interviews to get what she thinks, although in most of the cases it will not be the girl taking but her PR peoples butter up publicity around her. Look if your local radio will broadcast the concert. Most good stations “warm up” the community before the soloist arrival, playing the soloist’ recordings a few days ahead – that is a good way to assess own interests.
In the end if you care about the played music then any live event with the piece that you care is worth attention. I will extend very high probability that Ms. Jansen concert will be more fun then evening spent reading about horns and drivers at my site… :-)
