Chicago area booking agency for classical music attractions, concerts, opera, ballet, and recitals from 1940 to 1990.

Allied Arts Corporation, originally founded in 1940 by Warren E. Thompson and Edgar L. Goldsmith, was purchased by impresario Harry Zelzer, who had been one of their competitors, in 1948. Allied Arts after that was fully managed by Zelzer and his wife Sarah Schectman Zelzer until right before Harry Zelzer's death in 1979. Harry Zelzer had been booking classical music in New York and Chicago since the early 1930s. Sarah Zelzer wrote her memoirs (called Impresario) about her and her husband, which was published in 1990. Sarah Zelzer died in 1998.

For concert pianists and violinists, classical guitarists, visiting orchestras, touring dance companies, and opera stars, the Allied Arts Corporation was the Chicago company to work with, especially in the heyday from the 1950s through the 1970s. The Zelzers booked international stars of opera, ballet, dance, and classical music in Chicago, with some forays into pop and jazz (including, Judy Garland, Marlene Dietrich, The Kingston Trio, and Benny Goodman). They booked such famous stars as Andres Segovia, Vladimir Horowitz, Isaac Stern, Elisabeth Schwarzkopf, and Glenn Gould. Dance companies represented include the Ballet Russe de Monte Carlo, Sadler's Wells Ballet (now Royal Ballet), American Ballet Theatre, Bayanihan Philippine Dance Company, and Dance Theatre of Harlem. Notably, they also booked African-American opera singers such as Paul Robeson, Marian Anderson, and Leontyne Price, early in their careers. The Zelzers booked at the major venues in Chicago, including the Auditorium Theatre, Orchestra Hall, the Civic Opera House, and the Arie Crown Theatre, as well as some theaters in surrounding areas.

In 1978 the Zelzers gave the series they built to the Orchestral Association, the managing organization of the Chicago Symphony Orchestra. However, in the 1980s Sarah Zelzer resumed management responsibilities for the series for a short time. After 1990 the series evolved into CSO Presents and then Symphony Center Presents, both of which were managed by the Orchestral Association.
