I apologise for the title, but I couldn't think of anything more appropriate to capture my query.
You see, I noticed many artists of several different genres releasing material that was originally recorced by perhaps an orchestra in the 1960s or even the standard guitar, bass, vocals.... but they are still released as remasters in 2011. So the question I have is based on the fact that it appears oxymoronic (if that is a word) as surely the technology back then didn't capture the sound as well. Surely so much distortion emerges and frequencies captured are narrow. Sorry for the lack of technical terms.
Can anyone explain this? Is it along the similar lines to how World War I was filmed in colour but that couldn't be played back until technology existed to play it?
