Audio recordings of pianist Alexander Siloti

These are the only audio recordings of Alexander Siloti. The quality is very poor because they were recorded on a home record cutter around 1940. The records subsequently deteriorated when the Smithsonian attempted to recover the recordings. These recordings were made directly from the Smithsonian recordings where others on YouTube were from an audio cassette.
They are informal recordings of him improvising on the piano. I do not know what pieces he is playing. This video contains two versions of the recordings. The first version is without any filtering. The second version is with filtering. The unfiltered version has high level of noise. The filtered version has lower noise but some loss of the piano quality. Take your pick.
Unfiltered version (00:10 - 06:38)
Filtered version (06:38 - 13:06)
