Which orchestra performed with George Szell in the original release of the given excerpts?

The Cleveland Orchestra is the correct answer because George Szell served as the music director and conductor of this esteemed ensemble for over two decades, from 1946 until his death in 1970. During his tenure, he was pivotal in establishing the orchestra's reputation as one of the finest in the United States, celebrated for its precision and interpretative depth. The collaboration between Szell and the Cleveland Orchestra resulted in many influential recordings and performances that showcased the ensemble's unique sound and Szell's distinctive conducting style.

In contrast, the other orchestras listed were not associated with Szell in the explicit context of the original release of the excerpts referenced in the question. Each of these orchestras has its own notable history and conductors, but they did not collaborate with Szell in the same foundational way as the Cleveland Orchestra did. This key relationship solidifies why the Cleveland Orchestra is the correct choice.
