have a long history of local philanthropy and their funds were essential to provide necessary financing for several park features. Ticket prices for both the Harris Theater and the Pritzker Pavilion have been controversial. John von Rhein, classical music critic for the Chicago Tribune, notes that the theater's size poses a challenge to performers attempting to fill its seats, and feels that it overemphasizes high-priced events. In 2009–2010, the theater introduced two discounted ticket programs: a $5 lunchtime series of 45-minute dance performances, and a $10 ticket program for in-person, cash-only purchases in the last 90 minutes before performances. Once the pavilion was built, the initial plan was that the lawn seating would be free for all events. An early brochure for the Grant Park Music Festival said "You never need a ticket to attend a concert! The lawn and the general seating section are always admission free." However, when parking garage revenue fell short of estimates during the first year, the city charged $10 for lawn seating at the August 31, 2005, concert by Tori Amos. Amos, a classically trained musician who chose only piano and organ accompaniment for her concert, earned positive reviews as the inaugural rock and roll performer in a venue that regularly hosts classical music. The city justified the charge by contending that since the pavilion is an open-air venue, there were many places in Millennium Park where people could have enjoyed the music or the atmosphere of the park without having to pay. Use restrictions When Millennium Park first opened in 2004, Metra police stopped a Columbia College Chicago journalism student working on a photography project, and confiscated his film because of fears of terrorism. In 2005, Cloud Gate attracted some controversy when a professional photographer without a paid permit was denied access to the piece. As is the case for all works of art currently covered by United States copyright law, the artist holds the copyright for the sculpture. The public may freely photograph Cloud Gate, but permission from Kapoor or the City of Chicago (which has licensed the art) is required for any commercial reproductions of the photographs. Initially the city charged photographers permit fees of $350 per day for professional still photographers, $1,200 per day for professional videographers and $50 per hour for wedding photographers. The policy has been changed so permits are only required for large-scale film, video and photography
