In the United States, electronic dance music is known for selling three things: tickets, drinks, and black-market goods. And with the gold rush of the past few years, the numbers on those sales have skyrocketed.
What EDM had never sold to America in big numbers - not even during the late-'90s electronica boom - are recordings. On the face of it, that's not so surprising: It was often a deliberately - even aggressively - faceless movement where compilations outsold artist albums, and any money spent on music by most hardcore dancers went to small record shops, phat-pants boutiques, or merchants at parties, none of which report their sales to SoundScan.
Surprisingly, in the last year, that has changed.
