When it comes to big blockbuster tours, Arthur Fogel is the guy. The Canadian-born industry icon practically invented them. It was a big year for record-setting live music events, and other than Taylor Swift, Fogel’s fingerprints were on most of them: Beyoncé’s Renaissance Tour, U2’s now-iconic opening residency at The Sphere in Las Vegas, Madonna’s Celebration Tour and its 1.6 million-person topper in Rio de Janeiro, Brazil. “For me, it was an incredible year,” Fogel says in Billboard Canada’s Q&A. “To do all of those within a year was incredibly challenging and stressful, but each of them in their own way was greatly successful.” For fellow Canadian exec, Live Nation’s CEO Michael Rapino, the year might be stressful for a different reason: the U.S. Department of Justice’s just-filed antitrust lawsuit, accusing the company of anticompetitive business practices and a proposed separation from Ticketmaster. When it comes to power, Live Nation might just be too powerful.
