What do you think of crossover art considering classical music? I mean, when they take some classical pieces that are usually very famous, and then combine them with techno, dance, pop etc. elements?
For example, in Croatia we have a pianist, Maksim Mrvica, who apart from performing (which, I have an impression, he does rather seldom) makes crossover music with electronic and dance music. He says he's working on the popularisation of classical music with young people. So in this way he arranged Chopin's Revolutionary Etude, Grieg's Concerto, Rimsky-Korsakov's Flight of the Bumblebee, Liszt's Totentanz etc.
Personally, I don't like this music much. In case of Maksim, most of his fans are 12-15 y.o. girls who mostly like him because he's (by some criteria) good looking and wears weird clothes.
In general, I'm of opinion that a genre of music should remain a genre of music. One listening to crossover classical music certainly cannot say that he's heard a classical masterpiece, because there are very little similarities between that medley and the classical original. Fine, some jazz+Gregorian chant or Beethoven+techno arrangements are nice, but that then is a new type of music. I may be a purist, but that's my opinion. If one wants to hear classical music, than let him buy a real CD, listen to it in pure, authentic form, and if he/she cannot understand or even like it after listening to it for a couple of times, then classical just isn't for him/her.
