E.D.M.’s business outlook is much debated in the industry, and some acts, like Zedd and Madeon, are looking beyond a career as simply a performing artist, to producing other acts and working in film. (Skrillex is already scoring for Disney.)

“It is risky long-term to base your career around a narrow style that may turn out to be a fad,” Madeon wrote in an e-mail. “I’m currently producing records for other bands and artists that are not in the electronic world, and it’s extremely fun and fulfilling. It’s something I’ll probably do more of in the future.”

Earlier in the day Zedd and Skrillex visited Beatport’s Denver offices, mingled with employees and checked out the staff D.J. station. In his backpack Zedd carried a laptop, spare computer drives and a tangle of cables: all the gear he would need to perform.

Not long ago he had never been away from home for more than two weeks. Then it was six weeks, then two months, then six months. He, and his parents, are still coming to grips with the frenzied pace of his new life, he said.

“But I would never complain,” Zedd added. “My biggest dream is coming true.” Then he made his way to Red Rocks.
