I broke this off from the "digital evil, analog bodacious" thread because I think it deserves its own commentary.
I had mentioned that I was going to post a new song that some people would probably like and some people probably wouldn't. So, if I know in advance that people aren't going to like it, why would I post it?
Which got me thinking about why we record music. I always just say "it's a biological imperative for me" but I really think there are only two main reasons to record music.
1. The Rorschach test. Something comes out of me and ends up in a form where I can listen to it. It's very much like looking into myself and I often learn things. Like the song I mentioned, "On Mars," is not about my experiences on Mars But I realized that I feel very isolated sometimes, particularly now, and that's how those feelings manifested themselves...and it gave me insights into my subconscious I might not have accessed otherwise.
2. Communication with others. We have an experience and we want to share it, the same way we'd talk about experiences in a conversation. Musician interact with an audience and music just takes it to another level.
Music is called the universal language for a reason...and it is a language. Music doesn't need lyrics to convey meaning, just ask Bach or John Coltrane.
(Of course the third reason is to attract members of hte opposite sex, or same sex if you swing that way, but that's a whole other topic and not really the point of this thread.)
