hi ian no pun intended but i posted an item on another forum about french horns being an endangered instrument .i have played one, hellish difficult to pitch as i noticed the other day concert by the chicago symphony orchestra!anyway on your point about orchestras i am a playing musician i used to play violin but the main strength in my opinion of the berlin phil is its magnificent string section ,the whole orchestra was g reat under claudio abbado but simon rattle too progressive for most people ive spoken to .and thats a shame because the berlin phil vote on ,and pick ,there conductor.i think it was because rattle looks a bit like a young beethoven!!on orchestras of the world there is a thing called a diffinitive performance and the chicago symphony is there,also amsterdam ,phily ,vienna phil ,by diffinitive i mean the audience loved the tempi,marks of expression,soloist on top form etc ,and if these performances are recorded they will stand forever and become a benchmark for others.huge subject this but love it .KEEP MUSIC LIVE !GUEPE
