The Krannert Center for the Performing Arts is an educational and performing arts complex located at 500 South Goodwin Avenue in Urbana, Illinois and on the campus of the University of Illinois Urbana-Champaign. Herman C. Krannert, an industrialist who founded Inland Container Corporation and an alumnus of the university, and his wife, Ellnora Krannert, made a gift of $16 million that led to the Krannert Center's construction. Max Abramovitz, the architect who designed the facility, was also an Illinois alumnus. The center, often abbreviated as "KCPA," contains four venues with a combined seating capacity of about 4,000. The expansive main lobby features a floor made of teak from Thailand, which cost $1 million, and walls clad in marble from Carrara, Italy. The building opened in 1969. Performance facilities Foellinger Great Hall, with 2,078 seats, is the largest of the venues at the center and is known for its acoustics; it attracts world famous artists and ensembles to perform every year. Some noteworthy orchestras like the Chicago Symphony Orchestra and the Sydney Symphony have used the hall for recordings. The School of Music at the University of Illinois hosts many performances in this venue by students, faculty, the Sinfonia da Camera and the University of Illinois Wind Symphony. It is the main venue for the Champaign-Urbana Symphony Orchestra, the Professional Orchestra in Residence at the Krannert Center and the Sinfonia da Camera conducted by Ian Hobson. Dr. Cyril Harris, a noted acoustician and Emeritus Professor of Architecture at Columbia University designed the interior of the Foellinger Great Hall. His past projects include the Metropolitan Opera House in New York City and Powell Symphony Hall in St. Louis. Later projects include the mid-1970s renovation of Avery Fisher Hall at Lincoln Center and the late-1990s design of Benaroya Hall in Seattle. The design of the hall is almost perfectly symmetrical. There are no parallel surfaces in the room, instead all the surfaces are angled to ensure that the sound reflects back to the audience. This accounts for much of the hall's acoustic superiority. No amplification is necessary for instrumental music. Tryon Festival Theatre, with 974 seats on two levels, was primarily intended for operas and the acoustics are designed to favor vocal performances. It also hosts performances of ballet, dances, musicals and plays. This theater is equipped with a Sennheiser Audio System, computerized lighting control, sound reinforcement and recording capability.
