Led by partners Charles Attal, Charlie Jones and Charlie Walker, Austin-based C3 Presents was in 2011 the 13th-highest-ranked concert promoter in the world-grossing $71.3 million, according to Billboard Boxscore. C3 books and produces hundreds of shows annually in casinos and private spaces; those unreported events would easily move the company into the top 10. And those gigs pay well, usually at a higher rate than public shows. C3, which took home the top U.S. independent promoter honor at last year’s Billboard Touring Awards, also produced some of the highest-grossing festivals in 2011, according to Boxscore. Chicago’s Lollapalooza ranked third on the year-end tally, grossing nearly $20 million, while Texas’ Austin City Limits placed fourth with a gross of $15.4 million. Along with Lolla owners Perry Farrell and William Morris Endeavor, other 2011 achievements included launching the festival in Chile. A second South American Lollapalooza will debut in Brazil later this year. C3’s global reach recently expanded with the announcement that it partnered with Big Day Out festivals in Australia and New Zealand. C3 is in the ticketing business with the innovative Front Gate Tickets, and the company also has an artist management division.
