San Jose’s summer jazz festival calls itself the “largest free jazz festival in the United States.” But that designation may be about to change. The festival may have to start charging: $5 a person for an all-day pass. “The reason for the charge: rising operational fees coupled with a loss of corporate sponsors Ford, Chevron and Applied Materials. The festival costs almost $1 million and, much to their disappointment, organizers said, only $60,000 comes from a city that has just designated $4 million for a car race.”
