I do not have much inclination to the music from Rachmaninov. However I was sensitive to the mood from both theses pieces, which I already heard of course but did not care much about. I appreciated them better without the background noise, which I removed by means of digital processing. Processed files here attached.
Nice work with the noise reduction! Generally I don't like noise reduced files. It inevitably changes the overtones of the piano sound, and the result, while prettier, usually has less character. But this is discreetly done and works quite well.
In either case, I very much enjoyed these recordings.
