An interesting note on the auditorium: In 1960, Syria Mosque across the street was the usual venue for Pittsburgh Symphony performances. But when the Symphony made some high-tech ultra-high-fidelity recordings for Everest that year, conductor William Steinberg insisted on using the auditorium in Soldiers and Sailors Hall instead. He thought the acoustics were much better. Those Everest recordings are still regarded by connoisseurs as some of the most real-sounding symphonic recordings ever made.
