Good recommendation and reminder, Montepilot:
I recommend opening new records that you intend to keep for personal listening soon after purchase for inspection.
I'm unfortunately in that uncomfortable position of having many new records that I've opened for a visual inspection but have not been able to listen to due to our move. I'm keeping fingers crossed as I start going through them: cleaning and then listening.
I just looked online for the 45 rpm Ravel, "Rapsodie Espagnole" you mentioned above. I have the 33 rpm, but not the 45 rpm, and the only place I can find the 45 rpm is now asking $75 for it. Guess I should have gotten it a few years ago... If this is anything like the other 45 rpm Mercuries that Classic Records reissued (e.g., Prokofiev "Scythian Suite" and Stravinsky "Firebird"), I'm sure it's everything you describe. In each case, these 45s have been far superior to the rather disappointing 33 rpm versions.
Cheers,
