6. Russell Faibisch, Ultra Music Festival, Founder
A Nineties rave kid made good, Miami native Faibisch (along with then-business partner Alex Omes) staged the first Ultra Music Festival as a relatively low-key, daytime beach party with a small handful of stages in 1999. But by its third edition, Ultra had outgrown its old sandy spot, moving to mainland Miami and offering a stage for nearly every genre. It soon grew into a beast that became America's first massive, outdoor all-dance-music festival, and in its current, three-day incarnation remains the largest, boasting more than 330,000 attendees in 2013 (over two weekends). The spate of contenders in its wake – Electric Daisy Carnival and company – only spotlights Ultra's savvy foresight. These days, Faibisch presides over an international chain of branded festivals, including editions across Europe, Asia, South America, and now Africa, plus radio broadcasts and film premieres.
