I called a friend that was just about to go in to the Abilene Philharmonic... and he tells me the program this evening is..... Rimsky-Korsakov's Scheherazade.
Too much of a coincident, so I looked for my Mercury Living Presence copy, to find out it's mono in a stereo jacket.
No problem, to me mono sounds very lifelike as if you're sitting 30+ rows back.
I gotta say, there are some tonality things and hall ambience that mono recording do extremely well!!
My cover is from the 1959 pressing, but the record is actually the 1952 performance. Wow. Great performance.
