The emphasis on music concerts comes from the fact that very few music artists make a worthwhile income from sales of their music on physical media. The lack of any distribution structure means that there is little to no incentive for capital investment in artist development or music sales. There are no genuine record labels, with most of the companies that are referred to as labels being merely artist management companies. Because of these inadequacies, there is a severe strain placed upon musicians to find profitability and sustainability in making music.
