While the concert industry as a whole has struggled this summer, the festival business has remained steady. Coachella, in Indio, Calif., sold out, and C3 says that Lollapalooza’s ticket sales are strong.
“Festivals are a great value, and I think that’s why they are doing well this year,” Mr. Attal said. “You see 130-plus bands at a price that breaks down to $1.50 a band or so, instead of paying $80 to see two acts in an amphitheater.”
C3 has developed a reputation for running events smoothly, treating artists well and overstuffing their festivals with quality bookings and creature comforts. This year, for example, Lollapalooza’s food is overseen by the celebrity chef Graham Elliot Bowles (President Obama celebrated his birthday on Wednesday night at Mr. Bowles’s restaurant with Oprah Winfrey), leading to vendors with menu items like strawberry-pie shakes and Mr. Bowles’s own lobster corn dogs.
