Music is important because;
it's a way of experiencing and expressing emotions
It's connecting something in you to something outside you,
so it connects people to the world and it consoles those suffering or feeling disconnected from the world
It can be made solo or as part of a group event
It communicates and helps create/sustain community - eg in the Church, the choir, the brass band, the football ground, the bedroom
It's something that almost anyone can do, almost anywhere.
It's great to see people create their own music, not only for a career, but for pleasure of being creative and sharing the experience with friends, like the graffiti on the wall - messy, original, personal.
Much of the commercial "music" we are offered is brought to us by people who control the artists, the venues, the ticket sales, the merchandise and much of the media which promotes it.
It will last only as long as people have
confidence in the story they are sold.
...but people will not stop making their own noise, in their own way
Don't be such a stranger.
