"Live Music" vs "Recorded Music"... I've been to many (too many) live music shows where the half-deaf sound board guy totally ruined the experience. And a very few where it's great. That's rare and requires great music, great musicians, a great physical space, and a great position within that physical space.
A well-recorded live performance has emotion, wonder, humanity, and presence that a multi-tracked, processed recording can't have. And a well-recorded multi-tracked, processed recording has detail, intimacy, slam, and a kind of perfection that a live performance can't have.
But... this argument reminds me of my childhood in the 60's, when they brought in this crazy thing called a "Moog" and the teacher said, many people say, what it produces it not considered music by many professionals.
I'm tempted to argue that for most of us now, recorded music IS live music. At the very least, it's an art form unto itself. P Glass has always credited his engineers as musicians, and the good ones are. Their instruments may not have strings, drums, or mouthpieces, but a great sound engineer does as much to bring us close to the neurons in the composer's brain as a great pianist in a great hall.
I'd argue that if you can bring the composer/artists thoughts, feelings, intentions, in a live performance, in a physical venue - you've done your job well. If you do it thru technology and recording - you've done your job well.
There is some incredible music, that simply can't be performed live and in a physical space. What's wrong with that? Why confine art within the limitations of the past?
What I think we all agree on, is we don't like it when musical reproduction equipment tries to make everything you hear sound like the flavor of the month. The best reproducing equipment lets it be, what it was meant to be.
