This provides a fairly in depth look at the music industry and really spells out why these changes have happened. However, and not to discount the author's work, without providing the breadth of evidence in the article, this stuff is just super obvious. Technology has lowered the barrier to entry for all digital trades, quality and supply have skyrocketed while demand has stagnated(due to competition with internet/tv/apps etc) and the distribution platform and monetization strategy has changed. Coupled with widespread piurating the switch to live concert monetization is obvious as it can not be replicated.
