The fact that we don't have original recordings of classical music has always bothered me. Sheet music somehow lacks the "touch" of the composer. A complete and mastered recording is something unique and stuck in time, capturing the individual players, instruments, sound and everything else. Listening to Mike Oldfield's "Tubular Bells" (1973) evokes a particular feeling that, at least to me, cannot be replicated by someone playing it. It bothers me that the full output of the artist's mind couldn't be captured and somehow stopped in a single perfect execution, summing up the emotions that the composer wanted to express in a single frame. It's sad that I won't ever get to listen to a studio version of Tchaikovsky's "Piano Concerto No. 1" of the time it was composed, supervised by Tchaikovsky himself. It's like pretending a guitar cover video of your favorite guitar solo it's the same as listening to the original song. It isn't, no matter how good the covering player is. A copy cannot be superior to the original, even if it adds or changes something according to the player's mind, it's still a copy. Even the original composer playing his own song live does not and cannot express the same emotions as a recorded version of the song. This is obviously my own opinion (and a very unpopular one) on a necessarily subjective thing.
