'Creativity' is a criteria amongst many others. Not everyone is, nor wants to be, creative, and there is a lot of creative stuff that is really... well, let's just say 'not very good', eh..? Is music, already composed, never, ever, to be played again, by anyone..? Maybe not even by the original composer, if one is to be strict about it. What's wrong with reading aloud a Good Poem, for folk to enjoy..? What's wrong with playing Good Music for folk to enjoy..? What's wrong twith playing bad 'creative' music for folk to enjoy..? (Ignore that last bit; it's so rare...). If the Players wish to go out on a limb and play whatever their 'creativity' dictates, that's fine, and if anyone has the temerity to suffer it, good on 'em. I'd rather play my Schubert's Ninth for the umpteenth time, and hear again something I'd not heard in there hitherto. One day, I might even go for a different version, and see what the conductor and/or orchestra have managed to 'create' from this old soup.
To each his/her own, naturally.
