Early in his tenure as the Chicago Symphony Orchestra’s sixth music director, Fritz Reiner first led his friend and countryman Béla Bartók’s Concerto for Orchestra on October 13 and 15, 1955. “This wonderful score, a network of nerves spun and controlled by the most brilliant of nervous energies, was played as only great orchestras can play,” wrote Claudia Cassidy in the Chicago Tribune. “It is a superb work and a Reiner triumph.”

The following week, Reiner and the Orchestra committed their performance to disc on October 22; for RCA, Richard Mohr was the producer and Lewis Layton the recording engineer. In February 2016, Gramophone listed this release as one of the “finest recordings of Bartók’s music,” noting the “sheer fervour of Reiner’s direction . . . taut and agile . . . [his] precision and control is immediately apparent.”
