From That Ain’t Art, artist Mat Gleason answers questions about the art world for their readers. His advice is practical. My favorite bit, not quoted below, is that if you want a gallery show, make great art.
I am an artist. I feel I am ready for a gallery show, but I have never exhibited before. When I talk to galleries they seem snobby. What can I do?
Bathing and proper hygiene are the first order of business. After that, looking good and being rich cannot hurt too much either. But the reason they seem snobby to you is that you do not know them anymore than they know you. Get to know each other. Get to know the art world.
