Here is one that talks about how some artists go the route of signing with a large promoter like Live Nation who pays them a set fee and the artist is guaranteed that money no matter how many tickets get sold. In these cases it is mostly the promoters that set the prices, but there are several things that influence that price.

Here is an article that shows how the price of a concert ticket is broken down and who makes what from the sale. The artists, according to this story, pocket 74% of the face value of a ticket. When you control that amount of the earnings it is logical to assume you have a big say in the price of the ticket.

Here is one more that talks about ticket pricing overall. It basically says that the artists give the promoter a dollar amount they want to earn per show and the promoters then set out to determine a good ticket price that will make sure they bring in enough revenue to pay the artist, cover the costs and still make money.
