Responding to the link to a performance of Welte-Mignon piano
rolls 2168, 2169 and 2170) that was given in the 20.06.04 MMD:

Premier Sonate op.7 Pavel Khvostchinski

Wow!  What a wonderful piece of music!

I could discover nothing about the composer/pianist or his music
other than the fact that the rolls were made in Moscow, either
at the end of 1909 or the very beginning of 1910, and appeared
in catalogs starting in February 1910.

Does anyone have any more information?

John Cowles

 [ The 20.06.04 MMD article John Cowles refers to is Kevin McElhone's
 [ "Red Welte Rolls and Welte Book Wanted" and the performance that
 [ floored John was by the Russian composer whose name was given as
 [ Pavel Kvostchinski, although Kevin McElhone gave in his submitted
 [ posting variant spellings.
 [
 [ I think that the difficulty in identifying this composer or finding
 [ information about him may have more to do with transliterating or
 [ romanizing Russian names written with Cyrillic characters than with
 [ anything else.  This difficulty is shared by at least one writer on
 [ Russian composers whose book I found on the Internet.  He said in
 [ a footnote that he was unable to find information on the composer.
 [
 [ But a Wikipedia article, "Tschaikowsky (and Other Russians)," at
 [ https://en.wikipedia.org/wiki/Tschaikowsky_(and_Other_Russians) 
 [ lists him as Pyotr Abramovich Khvoshchinsky.  The webpage
 [ https://www.pianorarescores.com/archive/peter-khvoshchinsky-piano-sheet-music/ 
 [ shows Peter Khvostchinsky piano sheet music including his Piano
 [ Sonata Op. 7 No. 1, and it says "Peter Abramovich Khvoshchinsky
 [ was a Soviet Composer, he died in 1893."
 [
 [ And finally, three YouTube performances of his compositions are
 [ shown on Google in an entry titled "Pyotr Khvoshchinsky (Youtube
 [ piano pieces)."
