Oops! I am not sure how I missed that helpful info, thanks!
Here's the intersection between the catalogues:

The Reiner Sound
Rachmaninoff: Rhapsody on a Theme of Paganini - Falla: Nights in the Gardens of Spain (Rubinstein-Reiner-Jorda)

Khachaturian: The Masquerade Suite - Kabalevsky: The Comedians (Kiril Kondrashin)
Rozsa: Violin Concerto - Benjamin: Romantic Fantasy (Heifetz)
Lalo: Symphonie Espagnole (Henryk Szeryng)
Debussy: Iberia - Ravel: Alborado Del Gracioso, Valses Nobels Et Sentimentales (Reiner)
* included for Lt. Kije; Song of the Nightingale was included with Scheherazade in the Sony SACD series.
Edit: no. Symmetric difference? Whatever. The new ones. There.
