I happen to know many Greek colleagues of my generation. Met many of them in Germany, and some later through common friends, or concerts in Greece. I do have faith in this generation, a really talented one, with studies abroad. Most of the pianists for example between 25-35, the ones that perform more or less regularly, have studied in Academies and Universities in Europe. The reason I concider these studies important is not because they learned how to play an instrument, or how to make music. It is rather the fact that they got used to a different mentality than the one of the previous generations.
I talked to one of them last summer. One that I met very briefly here in Helsinki. He went to a concert last season, a kind of breakthrough for most Greek conductors, and he liked some of the concert's soloists. He offered the soloist to perform with the orchestra where the conductor assists. In theory, this is a noble and unique for the reality gesture. Practically the young soloist might wait a year or two until he plays with the orchestra.
Now, this gesture is something that I agree with. In general, many of my colleagues, soloists or conductors don't attend concerts in Greece. There are some exceptions but very few. It has happened to me once or twice (and I'm referring to colleagues that weren't freinds), the older I get obviously the less colleagues will be interested in listening to me. It is however a fact, that some persons in important positions couldn't care less about my playing, or for that matter anybody else's that they don't personally know... This raises the question: how do they decide who performs when and with whom, and where? I guess if they know you, you're lucky. And I'm not afraid to admit that this is how it worked with me in several occasions, though not always, not lately. Furthermore, in comparison with quite a few musicians I concider myself lucky, as far as performace opprtunities are concerned.
Anyway, listen to younger performers if you go to (are in) Greece, you might get surprised. Cheers!
