This parallel recording comtpares the very dry, precise studio sound (here in the acoustics of the Teldex studio, strings at studio orchestra strength and the sound of a New York Steinway from the 1950s), as can be heard in recordings with the composer in the 1930s, with a sound that one might expect in a modern concert hall (here the acoustics of the Berlin Philharmonic, with larger orchestral line-up and a current German Steinway D).
