Most artists that try to invent something new start with essentially no audience. They don't create that for the big bucks.
What I have noticed of this, and my readings seem to point to the reaction of people around someone in an uncharted direction like PG being a mix of "bemused but admirative and encouraging", and "ignored". And what proportion of the "peers" is now online? IG and such? (For an artist in my life, IG seemed to be an essential lifeline. A main connection.)
And they can all post videos of performances on YouTube. You don’t even need to have an orchestra perform a work for an extended time before you can find an audience. I would think that this would make it more likely for new composers to be able to find success than before. You don’t necessarily need to be in an NYC or Boston like before.
