WILL-Channel 12 turns its camera on the UI in two upcoming broadcasts. UI dancers will be showcased on Saturday's "New Expressions," the weekly performing arts program. The program, airing at 7 p.m., will include dances choreographed by dance professor Renee Wadleigh and professor emerita Beverly Blossom. Wadleigh's "Their Shadow on the Earth" premiered at the Illinois Dance Theater's "Celebration 25." Two excerpts from the Krannert Silver Jubilee performance are included in the program: Blossom's "Dad's Ties" and Martha Graham's masterpiece, "Panorama." The next episode of "Prairie Fire," Channel 12's cultural magazine series, will feature a musical noon-hour campus tradition. UI chimemaster Albert Marien and his assistants will talk and perform at 8 p.m. Aug. 11.
