Only being true to oneself will satisfy the communion of the artist's unique and also united spirit. Nowadays gallery owners here in Austria are very much selecting which artists they want to exhibit. So the mainstream is selected more or less depending where galleries are located. Some artists are out of the circuit, do not associate with the right kind of people, and are consequently cut out of potential success. We're not like a fraternity of on line orthodontists saving time and helping their clients by sharing the latest in bone medicine.
Artists are sovereign, yes, but also isolationist and sometimes pig-headed.
Many years ago I was living in the Chilcotin country in central British Columbia. I remember the wild horses visiting an old rancher at moonlight outside his house. They would call him out, and out he would come, give them a few apples, they would exchange a few words and snorts and just as quickly as they had arrived they thundered away into the darkness, back into the hills. We stayed in a very rough cabin, no running water, no electricity, no phone, no radio. Five hours over a rough road to the nearest store.
