Just let me specify that I think the artform of interpreting (and re-interpreting) a work is most definitely legitimate and appreciated. Different film versions and readings of a book, for example. I will never make an argument against re-interpreting works. That would be silly.
It’s just that – on a personal level – I’ve never really had the need for more than ONE version, IF and only IF that version is a good one. If I want to experience a given work, I’m content with ONE version I’m pleased with. I mean, I’m sure I have several versions of Beethoven’s 9th symphony – since Nick brought that up – scattered across my collection, but if I’m in the mood for that particular work, I’ll probably just go for the Karajan/Berlin Phil/DG CD I have, from 1977. That will satisfy my need for Beethoven’s ninth at any point in time.
